Kingdom Plantae main features in the form of question answers
- What is the Kingdom Plantae?
The Kingdom Plantae is a group of organisms that includes all plants, including algae, mosses, ferns, and flowering plants.
- What are the characteristics of plants in the Kingdom Plantae?
- They are multicellular and have cell walls made of cellulose.
- They are autotrophic, meaning they can produce their own food through photosynthesis.
- They have chloroplasts, organelles that contain chlorophyll and are responsible for photosynthesis.
- They reproduce via seeds or spores.
- Can you give an example of a plant in the Kingdom Plantae?
One example of a plant in the Kingdom Plantae is a rose bush (Rosa sp.). It is a flowering plant that has leaves, stems, and produces flowers and seeds.
- How do plants in Kingdom Plantae reproduce?
Plants in Kingdom Plantae reproduce sexually or asexually. sexually reproduction involves the union of male and female gametes to produce a seed which germinates to form a new plant. Asexual reproduction involves the production of spores or vegetative reproduction like the growth of runners or bulbs.
- Are all plants in Kingdom Plantae green?
No, not all plants in Kingdom Plantae are green. While the majority of plants are green because they contain chlorophyll, which is responsible for photosynthesis and gives plants their green color, some plants have adapted to lack chlorophyll due to their adaptation to their environment. For example, the cacti and succulents have adapted to desert environments and have adapted to lack of chlorophyll.
Heterotrophic Plants
- What are heterotrophic plants?
Heterotrophic plants are plants that cannot produce their own food through photosynthesis, and instead obtain it from other sources. They are also known as parasitic or saprophytic plants.
2. How do heterotrophic plants obtain food?
Heterotrophic plants obtain food by penetrating the roots, stems, or leaves of other plants, and absorbing nutrients directly from them. Some examples of heterotrophic plants are mistletoe, dodder, and Indian pipe.
3. Can you give an example of a heterotrophic plant?
One example of a heterotrophic plant is the mistletoe (Viscum album). It is a parasitic plant that attaches itself to the branches of trees and absorbs nutrients directly from the host tree.
4. How do heterotrophic plants survive without photosynthesis?
Heterotrophic plants survive without photosynthesis by obtaining the necessary nutrients from other organisms. They can be parasitic, meaning they attach themselves to a host plant and absorb nutrients directly, or saprophytic, meaning they obtain nutrients from dead organic matter.
5. Are all heterotrophic plants parasitic?
No, not all heterotrophic plants are parasitic. Some heterotrophic plants are saprophytic, meaning they obtain nutrients from dead organic matter. Examples of saprophytic plants include Indian pipe (Monotropa uniflora) and the corpse plant (Amorphophallus titanum).
Bladderwort and Venus Flytrap
- What is a Bladderwort?
A Bladderwort is a carnivorous plant species of the genus Utricularia, which comprises over 220 species and is found in freshwater and terrestrial habitats in almost every part of the world. They are aquatic or terrestrial plants that capture small aquatic animals such as Daphnia, rotifers, and small aquatic insects.
2. How does a Bladderwort catch its prey?
A Bladderwort catches its prey by means of small, modified leaves that form bladders. These bladders are modified to suck small aquatic animals by creating a vacuum in the bladder by closing its door-like trap, and opening it again to release water and prey.
3. What is a Venus Flytrap?
A Venus Flytrap is a carnivorous plant species of the genus Dionaea, which is native to subtropical wetlands on the East Coast of the United States. It captures insects and arachnids using modified leaves that form traps. These traps have sensitive trigger hairs that when touched, cause the trap to close, trapping the prey.
4. How does a Venus Flytrap catch its prey?
A Venus Flytrap catches its prey by means of modified leaves that form traps. When an insect or arachnid touches the sensitive trigger hairs on the surface of the trap, the trap closes quickly, trapping the prey. Once the prey is trapped, enzymes are released to break down the prey so that the plant can absorb the nutrients.
5. Are Bladderwort and Venus Flytrap the only carnivorous plants?
No, Bladderwort and Venus Flytrap are not the only carnivorous plants. There are many other carnivorous plants such as sundews, pitcher plants, and butterworts that have adapted to capture insects and other small animals as a source of nutrients.
Life Cycle of Plants Has Two Distinct Phases-The Diploid Sporophytic And The Haploid Gametophytic
- What are the two distinct phases of the life cycle of plants?
The two distinct phases of the life cycle of plants are the diploid sporophytic phase and the haploid gametophytic phase.
2. What is the diploid sporophytic phase?
The diploid sporophytic phase is the phase of the plant’s life cycle where the plant produces diploid (2n) cells that will give rise to spores. These spores will then develop into the next generation of the plant. This phase is also known as the sporogenic phase, and it includes the production of spores via meiosis in specialized structures such as anthers and ovules.
3. What is the haploid gametophytic phase?
The haploid gametophytic phase is the phase of the plant’s life cycle where the plant produces haploid (n) cells that will give rise to gametes. These gametes will then fuse during fertilization to form a diploid zygote, which will develop into the next generation of the plant. This phase is also known as the gametogenic phase, and it includes the production of gametes via mitosis in specialized structures such as antheridia and archegonia.
4. Can you give an example of a plant that goes through these two phases?
An example of a plant that goes through these two distinct phases is the fern. In the diploid sporophytic phase, the fern produces sporangia, which contain spores that will give rise to the next generation of ferns. In the haploid gametophytic phase, the fern produces gametangia (antheridia and archegonia) which contain gametes that will fuse during fertilization to form a diploid zygote that will develop into the next generation of ferns.
5. How are these two phases related to each other?
These two phases are related to each other because they make up the life cycle of a plant. The diploid sporophytic phase produces spores that will give rise to the next generation of the plant, while the haploid gametophytic phase produces gametes that will fuse during fertilization to form a diploid zygote that will develop into the next generation of the plant. Therefore, these two phases are essential for the reproduction and continuation of the plant species.
Alteration of Generation
- What is the Alteration of Generations?
The Alteration of Generations is the alternation of a multicellular diploid organism (sporophyte) and a multicellular haploid organism (gametophyte) in the life cycle of plants and some algae. This alternation of generations allows for the separation of the reproductive and vegetative functions and enables the organism to take advantage of different environmental conditions.
2. What is the significance of Alteration of Generation?
The significance of Alteration of Generation is that it allows for the separation of the reproductive and vegetative functions in the life cycle of plants and some algae. The diploid sporophyte is responsible for producing spores via meiosis, while the haploid gametophyte is responsible for producing gametes via mitosis. This separation allows the organism to take advantage of different environmental conditions and increases the chances of survival and reproduction.
3. Can you give an example of a plant that goes through the Alteration of Generation?
An example of a plant that goes through the Alteration of Generation is a fern. In the diploid sporophyte phase, the fern produces spores via meiosis in structures called sporangia. These spores then germinate to form the haploid gametophyte phase, which produces gametes via mitosis in structures called antheridia and archegonia. The gametes then fuse during fertilization to form a diploid zygote which develops into the next generation of ferns.
4. Are all plants have Alteration of Generation?
No, not all plants have the Alteration of Generation. Angiosperms, also known as flowering plants, have a different pattern of reproduction called the Embryophytic Life Cycle. In this cycle, the diploid sporophyte phase and the haploid gametophyte phase are both present but are fused together in one organism. These plants have specialized reproductive structures such as flowers and fruits which makes them different from other plants that have the Alteration of Generation.
5. How does the Alteration of Generation help in the reproduction of plants?
The Alteration of Generation helps in the reproduction of plants by allowing the separation of the reproductive and vegetative functions. This separation allows the organism to take advantage of different environmental conditions, which increases the chances of survival and reproduction. The spores produced in the diploid sporophyte phase can germinate in a wide range of environmental conditions, while the gametes produced in the haploid gametophyte phase can fertilize and form a zygote in specific environmental conditions. This increases the chances of successful reproduction and continuation of the species.
