Cells (1B 6) updated Flashcards
What is the function of a vacuole?
To store food, liquids and waste materials
What is the cytoplasm?
-It is a jelly-like substance that fills a cell.
- It is where most of chemical reactions take place.
What is the function of a nucleus?
It controls all cell actives that take place within a cell.
It is essential for cell division.
What is the function of the cell membrane?
Controls the movements into and out of the cell.
What is the function of the Cell wall?
-It is rigid and gives the cell a regular shape
-protects and supports the entire cell.
What is the function of the Chloroplast?
contains chlorophyll which allows photosynthesis to take place and make food for the plant.
*How is a tissue formed
Composed of a group of
cells with similar
structures which work
together to perform a
specific function
**How is an organ formed?
Composed of different
types of tissues, that
work together for a
specific function.
*How is an organ system formed?
Composed of many different
organs that perform
their individual specific
functions.
The different organs
work together for the
system to perform a
specific function.
*How is an organism formed?
The human is an organism made up of all the organ systems working together to perform various functions.
What is present in both animal and plant cells.
Cell membrane, cytoplasm, nucleus and vacuole
What is found in a plant cell but not found in an animal cell?
Cell wall and chloroplast
What is the division of labour in a leaf? (multicellular organism)
Different tissues that have specific functions work together in a coordinated way
OR
Different tissues work together/ in a coordinated way to perform a specific function.
What is the division of labour at cellular level? ( in a cell )
Different parts of a single cell perform different functions in a coordinated way to work more efficiently.
