Yeah? why wouldn't it be. It can create energy just from light and we can harness it in solar panels.
Answer A:
1. Spiral chloroplast:
This organelle help in photosynthesis, because it contain green pigment called chlorophyll in which water and carbon dioxide combine in the presences of sun light to prepare glucose.
2. Cell wall:
It is chemically composed of<span> an outer layer of pectin and an inner layer of cellulose. It provide rigidity and shape to spirogyra cell.</span>
Answer B:
The other parts which are not labelled include mucilage, cytoplasm, pyrenoids, cytoplasmic strand.
Answer C:
Function of pyrenoid:
<span>Each chloroplast strand has several round bodies called 'pyrenoids', which are responsible for starch production.
</span>Function of mucilage:
Mucilage help in retaining water in cell.
1.)Coral reefs are busy underwater ecosystems. Some people call them the “rainforests of the sea.” The corals look like rocks but actually are animals. They have hard calcium carbonate skeletons like clams. They form a base for lots of other organisms to live. You’ll find crabs, sea stars, worms, clams, sponges, jellies, sea turtles, and lots of fish. Coral reefs are complicated and very fragile. They are easily affected by pollution.
2.) Tropical rainforests are near the equator where it’s almost always warm and wet. These are the key ingredients for making lots of lush plants and trees. Half of the world’s plants and animals live in tropical rainforests. It’s a very busy ecosystem with many kinds of plants, animals, fungi, and microscopic organisms. Many of them live here and nowhere else.
3.) In the world’s many deserts, there is very little rain. The land is very, very dry. Here, living things have creative ways of finding and saving water. Cactuses are very good at storing water. They can live without rain for months. The kangaroo mouse lives in the Nevada desert. It rarely drinks water. It can get its water from the food it eats.
Answer:
The correct answer is - option C. Deep.
Explanation:
The river with a narrow river channel found in shallow depth rivers that show relatively faster water flows than the deeper river that are slow in the water flow. In the shallow rivers sediments found in suspended mode and transported to the sea or delta and deposited there.
In deeper rivers, the sediments found deposited in the rivers which is helpful for the fishes for their nutrients as they feed on these sediments.
Thus, the correct answer is- option (C).
The first answer Is A and the second answer is also A
