2. This cytoplasm of the cells of a tomato plant contains organelles X having different pigments which impart different colours to the leaves of tomato plants and its fruits. (A) what is the general name of the organelles X ?
(B) what is the -
(1) name
(2) colour
(3) function of organelles X present in the leaves of tomato plant ?
Answers
Answer:
white tomato
Explanation:
Answer:
(A) The general name of the organelle X is Plastids. Plastids are pigment containing double membrane organelles which give colour to cells.
(B) –
(1) The name of the plastids present in the tomato leaves is chloroplast and the name of the plastids present in tomato fruit is chromoplast.
(2) The colour of the plastids are green in the leaves and red in the fruits (tomatoes).
(3) Function of plastids is to provide cplour to the cells. The most important plastids found in leaves are choroplast. Chloroplast are present in mesophyll in plant cells which help in the process of photosynthesis.
Extra Information:
There are many types of plastids classified on the basis of the pigments produced by them.
The following are the types of plastids -
- Leucoplasts are colourless plastids which help in storage of food.
- Chromoplasts are coloured plastids present in fruits and flowers. These plastids contain pigments like carotene, etc.
- Chromoplasts are green coloured pigments which help in the production of sugar by the process of photosynthesis with the help of sunlight and certain enzymes.
- Proteinoplasts is a type of leucoplast, it stores proteins.
- Gerontoplasts are plastids present in leaves that are no more producing sugar by the process of photosynthesis. These are mostly found in ageing leaves.
- Amyloplasts is a type of leucoplast, it stores starch.
