Organization Of Life Flashcards
(24 cards)
What is the function of a plant cell wall?
To provide structure and support to the cell.
What is the function of a mitochondria in animal cells?
To generate energy in the form of ATP through cellular respiration.
What is the function of a chloroplast in plant cells?
To conduct photosynthesis and produce energy for the cell.
What is the function of the nucleus in both animal and plant cells?
To control the cell’s activities and store genetic material.
What is the function of ribosomes in cells?
To synthesize proteins.
What is the function of the Golgi apparatus in cells?
To modify, sort, and package proteins for transport.
What is the function of the endoplasmic reticulum in cells?
To synthesize lipids and proteins, and transport materials within the cell.
What is the function of lysosomes in animal cells?
To break down waste materials and cellular debris.
What is the function of the vacuole in plant cells?
To store water, nutrients, and waste products.
What is the function of the cytoskeleton in cells?
To provide structure, support, and facilitate cell movement.
What is the function of the cell membrane?
To control the movement of substances in and out of the cell.
What is the function of the nucleolus in cells?
To produce ribosomes.
What is the function of peroxisomes in cells?
To break down fatty acids and detoxify harmful substances.
What is the function of the cytoplasm in cells?
To support and suspend organelles within the cell.
What is the meaning of ‘mitosis’?
The process of cell division that results in two identical daughter cells.
What is the meaning of ‘diffusion’?
The movement of molecules from an area of high concentration to low concentration.
What is the meaning of ‘osmosis’?
The movement of water molecules across a semi-permeable membrane.
What is the meaning of ‘phagocytosis’?
The process by which a cell engulfs and digests particles.
What is the meaning of ‘exocytosis’?
The process by which a cell releases substances out of the cell.
What is the meaning of ‘endocytosis’?
The process by which a cell takes in substances by engulfing them.
What is the meaning of ‘cytokinesis’?
The division of the cytoplasm to form two separate daughter cells.
What is the meaning of ‘organelle’?
A specialized subunit within a cell that has a specific function.
What is the meaning of ‘plasma membrane’?
The semi-permeable membrane that surrounds the cell and controls what enters and exits.
What is the meaning of ‘vacuole’?
A membrane-bound organelle that stores water, nutrients, and waste products.
