Introduction
A chloroplast is a membrane-bound organelle found primarily in plant and algal cells that conducts photosynthesis, capturing sunlight and converting it into energy.
Chloroplasts, which are organelles found in plants and algae, have many functions, including :
1. Photosynthesis
2. Fatty acid and amino acid synthesis
3. Immune response
Structure
Chloroplast Overview - Chloroplasts are plastids found in plant cells, responsible for photosynthesis, and typically have an oval or biconvex shape.
Membrane Structure - They feature a double membrane structure, consisting of an outer and an inner membrane, which encloses a fluid-filled space known as the stroma.
Thylakoid System - Inside chloroplasts, there is a complex system of thylakoids, which are membrane-bound compartments that contain chlorophyll and are essential for the light-dependent reactions of photosynthesis.
1. What is the role of chlorophyll in chloroplasts?
2.Where do the light-dependent reactions occur in the chloroplast?
3.Where do the light-independent reactions (Calvin cycle) take place?
4.What are grana and what is their function?
5.What is the stroma and what occurs there?
What are the key structural features of chloroplasts that support their function in plant cells, and how do these features facilitate the synthesis of glucose?
