2.1.2 Cell structure and function (T/F)

The cell is the fundamental unit of life in all living organisms.

The plasma membrane is permeable to all substances.

Cell walls are present in both plant and animal cells.

The cytoplasm is the site of most metabolic reactions in the cell.

The nucleus contains chromatin, which carries genetic information.

Plant cells typically have one large central vacuole for storage and maintaining turgidity.

Ribosomes are involved in the synthesis of lipids and steroids.

Mitochondria are known as the powerhouses of the cell because they produce ATP through aerobic respiration.

The Golgi apparatus is responsible for packaging and transporting proteins and lipids.

Lysosomes are found in both plant and animal cells and contain hydrolytic enzymes.

Centrioles are present in plant cells but absent in animal cells.

Chloroplasts are the site of photosynthesis in plant cells.

The endoplasmic reticulum (ER) is a network of membranes involved in protein and lipid synthesis.

Food vacuoles in cells store genetic information.

Electron microscopes use electron beams and magnetic fields for high magnification.

Plant cells store carbohydrates as glycogen, while animal cells store carbohydrates as starch.

The nucleus is involved in controlling all cellular activities and cell division.

Smooth ER is responsible for detoxification and glycogen breakdown.

Chromatin condenses into chromosomes during cell division.

Contractile vacuoles are found in plant cells to regulate water balance.
