Question

1. Which cell organelle is necessary for photosynthesis?


2. Name different types of Plastids. Also write their functions?


3. Explain photosynthesis in brief?


4. Which plastid has chlorophyll in it? Name two cell organelles that have their own DNA .


5. Which gas is released out and taken up by the plant from atmosphere in photosynthesis?​

Answer 1

Answer:

1. chloroplast

2. plastids are classified as ..

a) Chloroplasts - They are the sites for synthesizing food by the process of photosynthesis

b)Chromoplasts - Chromoplasts have carotenoid pigments that allow different colours that you see in leaves and fruits. The main reason for its different colour is for attracting pollinators.

c)Gerontoplasts- Geronoplasts refer to the chloroplasts of the leaves that help to convert into different other organelles when the leaf is no longer using photosynthesis usually in an autumn month.

d)Leucoplasts- They are mostly used for converting amino acids and fatty acids.

3.Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

4.chloroplasts have chlorophyll in it .....two organells having their own dna are mitochondria and nucleus

5.in photosynthesis carbon dioxide is taken in and oxygen is given out ......

hope it helped u

Answer 2

The questions can be answered as follows:

Explanation:

• 1. The organelle that is necessary for photosynthesis is chloroplast.
• 2. The different types of plastids are chromoplast, chloroplast, gerontoplast, leucoplast.
• Chloroplast are double membrane organelles in which the process of photosynthesis occurs. Chromoplast gives colour to leaves and fruits. Gerontoplasts are chloroplast from the month of autumn when chloroplast is converted into different organelles. Leucoplast are colorless and serve as reservoirs for starches, lipids, and proteins.
• The plastid that has chlorophyll in it is the chloroplast. Two cell organelles that have their own DNA is the mitochondria and chloroplast.
• Carbon dioxide is taken up by the plants and oxygen gas is released.
