Q.

What characteristics distinguish algae from other protists?

Q. Read the following statements and identify the correct option(s) given.
I. A prokaryotic cell lack nuclear membrane, chloroplasts, mitochondria, microtubules and different kinds of pili.
II. In a eukaryotic cell, the nuclear membrane, chloroplast, mitochondria and pili are present.
III. In a prokaryotic cell, the ribosome is of 70S type and in mitochondria of the eukaryotic animal cell, the ribosome is of the 80S type.

Q. control and coordination in plant in simple words

Q.

Raghav kept a plant in a dark room for a week. The leaves started to look white and waxy. His mother advised him to keep the plant in a place where there was light directly falling on the plant. So he replaced the plant on the window sill where there was direct sunshine. The leaves turned green again. Which of these organelles do you credit for this change?

1. Plasmid

2. Plastids

3. Vacuole

4. Endoplasmic reticulum
