2.1 Cell Structure & Function Flashcards
Organelles found in both animal and plant cells.
- Nucleus
- Mitochondria
- Cytoplasm
- Plasma membrane
The organelle that controls the movement of substances in and out of the cells.
Plasma membrane
The organelle that stores genetic information.
Nucleus
Organelle found only in a plant cell.
- Cell wall
- Vacuole
- Chloroplast
Organelle found only in an animal cell.
Centriole
Organelle that produces protein.
Ribosome
Organelle that contains the hydrolytic enzyme that functions to digest worn organelles.
Lysosome
Site for energy generation.
Mitochondria
Organelle that serve as centres for the processing, packaging and transport of carbohydrates, proteins, phospholipids and glycoproteins.
Golgi apparatus
Organelle that involves in the detoxification of drugs and poisons.
Smooth endoplasmic reticulum
Which of the following cells contain many mitochondria?
I. Sperm cells
II. Muscle cells
III. Cells of shoot apical meristems
IV. Cells of root apical meristems
All
What will happen if there is a cell that does not contain endoplasmic reticulum?
I. The cell is unable to produce extracellular enzymes
II. The cell is unable to transport lipids and steroid
III. The cell is unable to undergo respiration
IV. The cell is unable to detoxify drugs and poisons
I, II & IV
What is the cell that has abundant Golgi apparatus and endoplasmic reticulum?
- Sperm cell
- Meristems cell
- Muscles cell
- Pancreatic cell
Pancreatic cell
Plant cell | Animal cell
I. Has chloroplast | Has no chloroplast
II. Has no cell wall | Has cell wall
III. Has large vacuole | Has small vacuole in lower animal cells
IV. Has nucleus | Has no nucleus
I & III
Animal cell has small vacuole in lower animal(Amoeba sp.,Paramecium sp.)
Which of the following exist in both plant cells and animal cells?
- Chloroplast
- Centriole
- Mitochondria
- Cell wall
Mitochondria
Chloroplast
Which of the following cells do not have this organelle?
I. Potato cell
II. Onion cell
III. Spinach cell
IV. Lettuce cell
I & II
A pair of small cylindrical structures of microtubules and found only in animal cells.
- Golgi apparatus
- Lysosome
- Chloroplast
- Centriole
Centriole
What is the function of mitochondria in a cell?
- Synthesis lipids
- Synthesis proteins
- Release energy
- Use energy
Release energy
What is the layer that separates the cytoplasm from the nucleus?
- Protoplasm
- Cell membrane
- Nuclear membrane
- Permeable membrane
Nuclear membrane
*Y is a dense sturcture containing chromatin within the nucleus. *
What is structure Y?
- Nuclues
- Nucleolus
- Chromosome
- Mitochondrion
Nucleolus
Which of the following structures have a partially permeable membrane in a plant cell?
- cell wall | vacuole
- cell wall | plasma membrane
- vacuole | plasma membrane
- plasma membrane only

What is the function of the Golgi apparatus?
- As a control centre of cell activities
- As a site of protein synthesis
- Facilitates movements of the synthesised materials from one cell part to another
- As a ‘collection’ and ‘distribution’ centre of the synthesised cell materials in the form of granular secretions
4
Explain the function of cell wall.
Provides:
- solid shape
- mechanical support to cell
- protection to cell
What is the main characteristics of plasma membrane?
- partially permeable
- made of proteins and phospholipids
Give two examples of the cell sap content.
- Water
- Mineral salts
- Enzymes
- Organic acids
- Amino acids
- Sugar
pick only 2
Which of the following carries a function to synthesis proteins?
- centriole
- mitochondria
- ribosome
- plasma membrane
ribosome
Structure R is usually found in the cell of green platns.
Explain the importance of structure R to green plants.
Structure R is the chloroplast. It’s function is to absorb light and converts it to chemical energy during photosynthesis.
