answer and question
Q1-What is chromatin network?
Q2-What are ribosomes?
Q3-state the various funtion of a leaf?
Answers
Answer:
The chromatin is the network of the cell nucleus, which contains all the DNA of the nucleus of the cell. The DNA in the nucleus is packaged by the histone proteins histones. The protein and DNA complex is called chromatin. Chromosomes, consisting of chromatin, are found within the nucleus
ribosome is a cell organelle. It functions as a micro-machine for making proteins. Ribosomes are composed of special proteins and nucleic acids. ... Ribosomes are found 'free' in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER.
As one of the most important constituents of plants, leaves have several essential functions:
Photosynthesis. ...
Transpiration. ...
Guttation. ...
Storage. ...
Defense. ...

Answer:
(1) The chromatin is the network of the cell nucleus, which contains all the DNA of the nucleus of the cell. The DNA in the nucleus is packaged by the histone proteins histones. The protein and DNA complex is called chromatin. Chromosomes, consisting of chromatin, are found within the nucleus.
(2) A ribosome is a cell organelle. It functions as a micro-machine for making proteins. Ribosomes are composed of special proteins and nucleic acids. ... Ribosomes are found 'free' in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER.
(3) Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.
