Exploring Cells and Tissues

What is the basic unit of life?

• Atom

• Tissue

• Cell

• Organism

What are the two main types of cells?

• Bacterial cells and Viral cells

• Animal cells and Plant cells

• Prokaryotic cells and Eukaryotic cells

• Stem cells and Somatic cells

What is the function of the cell membrane?

• The cell membrane regulates the movement of substances in and out of the cell.

• The cell membrane acts as a site for protein synthesis.

• The cell membrane stores genetic information.

• The cell membrane provides energy for cellular processes.

What is the role of mitochondria in a cell?

• Mitochondria are responsible for protein synthesis.

• Mitochondria produce energy (ATP) for the cell.

• Mitochondria store genetic information for the cell.

• Mitochondria regulate cell division and growth.

What type of tissue connects different parts of the body?

• Connective tissue

• Epithelial tissue

• Nervous tissue

• Muscle tissue

What is the primary function of epithelial tissue?

• To produce hormones

• To facilitate nutrient absorption

• To store energy

• The primary function of epithelial tissue is to protect and cover surfaces.

How do plant cells differ from animal cells?

• Plant cells lack a nucleus, while animal cells have one.

• Animal cells have large central vacuoles, while plant cells do not.

• Plant cells have a cell wall, chloroplasts, and large central vacuoles, while animal cells do not.

• Animal cells have a cell wall, chloroplasts, and large central vacuoles.

What is the function of red blood cells?

• To store nutrients and vitamins.

• To produce insulin in the pancreas.

• To fight infections in the body.

• The function of red blood cells is to transport oxygen and carbon dioxide in the body.

What type of tissue is responsible for movement?

• Epithelial tissue

• Nervous tissue

• Connective tissue

• Muscle tissue

What is the significance of stem cells in biology?

• Stem cells are not involved in any form of healing.

• Stem cells are only found in plants.

• Stem cells are significant in biology for their ability to differentiate into various cell types and their role in tissue repair and regeneration.

• Stem cells can only replicate the same type of cell.
