Density of certain cell components and specialised cell functions

Cell component found in abundance: Mitochondrion

1. Sperm cell

2. Muscle cell (e.g. flight muscles in insects and birds)

3. Plant meristem cell

Sperm cell

• Requires a lot of energy to swim towards the uterus and Fallopian tube to fertilise the secondary oocytes

Muscle cell (e.g. flight muscles in insects and birds)

• Requires a lot of energy to contract and relax to enable movement and flight

Plant meristem cell

• Requires a lot of energy to carry out active cell division process to produce new cells

Cell component found in abundance: Chloroplast

1. Palisade mesophyll cell

2. Spongy mesophyll cell

Palisade mesophyll cell & Spongy mesophyll cell

• Absorbs more sunlight to carry out photosynthesis

Cell component found in abundance: Rough endoplasmic reticulum & Golgi apparatus

1. Pancreatic cell

2. Goblet cell in intestinal epithelium and respiratory tract

3. Liver cell

Pancreatic cell

• Increases synthesis and secretion of digestive enzymes

Goblet cell in intestinal epithelium and respiratory tract

• Produces mucus

Liver cell

• Metabolises carbohydrates

• Detoxification of drugs and poisons
