Study Notes
Chloroplasts
- The primary function of chloroplasts is to perform photosynthesis, generating energy for the plant cell through light-dependent reactions.
- Chloroplasts are distinguished from other plastid types like leucoplasts and chromoplasts by their ability to perform photosynthesis and contain the pigment chlorophyll.
Chlorophyll
- Chlorophyll is a green pigment responsible for absorbing light energy, which is then used to fuel photosynthesis in chloroplasts.
Chloroplast Inheritance
- During cell division, chloroplasts are inherited by daughter cells through a process called binary fission, where the chloroplast divides and each daughter cell receives a copy.
Environmental Factors
- Environmental factors such as light, temperature, and water strongly influence the behavior of chloroplasts within plant cells, affecting photosynthesis and plant growth.
Cell Walls
Plant Cell Walls
- The primary component of the cell wall of terrestrial plants is cellulose, a complex carbohydrate.
Bacterial Cell Walls
- The cell wall of bacteria is composed of peptidoglycan, also known as murein.
Algal Cell Walls
- The cell wall of algae is composed of cellulose, similar to terrestrial plants.
Fungal Cell Walls
- The cell wall of fungi is composed of chitin, a polysaccharide.
Discovery of Cell Walls
- The cell wall of plants was first observed and named by Matthias Jakob Schleiden in 1839.
