Answer: The non-vascular plant group are

A) Chlorophytes

B) Charophytes

C) Bryophytes

Explanation:

Charophytes, Chlorophytes and

Bryophytes are those plants having multicellular body and doesn't have a vascular bundle i. e. xylum and phloem. In vascular plants, xylum ia is responsible for the transportation of water and phloem is responsible for the transportation of food materials from one part to another. These bundles are absent in Chlorophytes, Charophytes and Bryophytes.

This example reflects the food chain.
<span>The food chain describes relationships among the organisms by showing how the organisms are related to each other by the food they eat. The food chain contains levels and each of them presents a different trophic level (position of the organism in that chain). There is reliable energy transfer through each stage of the chain. Not all the energy at one stage is absorbed by the organism at the next stage but, the amount of energy from one stage to another decreases.</span>

Answer:

1.

Explanation:

Xylem cell is a plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

2. Phloem is the vascular tissue in charge of the transport and distribution of organic nutrients. The phloem is also a pathway to signaling molecules and has a structural function in the plant body.

3. Stomata are composed of a pair of specialized epidermal cells referred to as guard cells. Stomata regulate gas exchange between the plant and environment and control water loss by changing the size of the stomatal pore.

4. Guard cells optimize leaf gas exchange in response to changing environmental conditions and their turgor is controlled by alterations in atmospheric CO2 concentration, light intensity, humidity, and the drought hormone abscisic acid.
