Explanation / Answer
SER- Function - synthesis of phospholipids and cholesterol, helps in the detoxification of compounds produced in metabolic processes. Liver SER contains enzymes called cytochrome P450, which catalyze the breakdown of carcinogens and other organic molecules. The SER in muscle cells, known as the sarcoplasmic reticulum, releases calcium ions from the cytoplasm. Found in both animal and plant cells
Golgi- Golgi bodies take proteins and newly formed materials, package them and send them to other parts of the cell.found in both plant and animal cells
Lysosomes- Lysosomes are small sac-like structures surrounded by a single membrane and containing strong digestive enzymes which when released can break down worn out organelles or food. Plant cells do not have lysosomes
Peroxisomes- These structures take care of toxins. They do this so the cell isn’t poisoned by these materials.ound in both plant and animal cells.
Central Vacuole - The central vacuole is a large fluid-filled vacuole found in plants.
Chloroplasts are organelles, specialized compartments, in plant and algal cells. The main role of chloroplasts is to conduct photosynthesis.
Mitochondria are the powerhouses of the cell. This is where food is converted to energy.found in both plant and animal cells
Cell wall - The cell wall is a rigid organelle composed of cellulose and lying just outside the cell membrane.? Helps to hive cell rigid shape and protects it. Found only in plants.
