Question

True or false . 1.) Photosynthesis in the plant like cactus takes place in roots 2.) Parasites do not contain chlorophyll. 3.) During photosynthesis solar energy is converted into chemical energy. Choose the correct answer 1.) All green plants are (a) heterotrophs (b) autotrophic (c) parasites (d) symbiotic

Answer 1

Answer:

1. False

2.) True .

3.)True

Explanation:

1.  Because in cactus photosynthesis is mainly done by stem and other green parts of plants. Leaves are developed into spines to reduce water loss. Roots are not involved in photosynthesis...

2. Parasites such as dodders, which is a kind of morning glory, and cuscuta, are entirely devoid of chlorophyll and rely entirely on the host for food.

3. Because the process of photosynthesis involves solar energy which is converted into the food for plants ( as photosynthesis is a chemical energy) . So, solar energy is converted into chemical energy during the photosynthesis.

Hope it helps...

Answer 2

The following statements are stated as true or false:

1. Photosynthesis in the plant like cactus takes place in roots.
   This statement is false. Cactus do not have leaves where photosynthesis usually takes place. Instead, the spines are there are modified versions of leaves. The green stems are filled with chloroplast that allows photosynthesis to occur in plants like cactus. Hence, photosynthesis in cacti takes place in their stems and not their roots.
   
2. Parasites do not contain chlorophyll.
   This statement is true. Parasitic plants lack chlorophyll in them. Therefore, they cannot make their food and derive nutrition from the host plants. Parasitic plants very rarely can photosynthesize.
   
3. During photosynthesis, solar energy is converted into chemical energy.
   This statement is true. The solar energy gets trapped during photosynthesis by the plants and they are harvested to convert into a chemical form of energy. This chemical energy is in the form of important nutrient glucose with the help of water and the utilization of carbon dioxide.

The correct answer is All green plants are (b) autotrophic. Autotrophs are the primary producers in the complex food web. They make their food through the process of photosynthesis. Hence, the correct answer will be (b) autotrophic.
