Cells and their organelles:

Question 1

Cell Theory

Answer 1

All living things are composed of cells
All cells come from pre-existing cells
Cells are the basic units of structure and function in an organism

Question 2

Distinguish between the structures of prokaryotic and eukaryotic cells.

Answer 2

Eukaryotic cells are cells containing membrane-bound organelle Mitochondria present

prokaryotic cells do not have any membrane-bound organelles Mitochondria absent

Question 3

Chloroplast vs. Mitochondria structure and function

Answer 3

Mitochondria are the “powerhouses” of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They’re responsible for capturing light energy to make sugars in photosynthesis.

Question 4

plant cell basic organelle structure

Answer 4

Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts.
The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection.
The central vacuole maintains turgor pressure against the cell wall.
Chloroplasts capture light energy from the sun and use it with water and carbon dioxide to produce sugars for food.

Question 5

Animal cell basic organelle structure

Answer 5

Organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles. Ribosomes are not enclosed within a membrane but are still commonly referred to as organelles in eukaryotic cells.
