CELL FUNCTION Flashcards
- cells are the fundamental structural
units of all living things - presence of cells in our bodies can be
compared to the presence of bricks in
construction
CELL FUNCTION
What is under Subcellular Structure?
Plasma, Organelles, Homeostasis and Nucleus
It provides protection for cell: boundary bet. cells & environment.
PLASMA
Small structure within the cytoplasm that
carry out functions necessary to maintain
homeostasis in the cell.
ORGANELLES
The process by which a living organism
maintains internal stability while adapting to
changing external conditions.
HOMEOSTASIS
It’s the control center of the cell. DNA
Replication, Transcription; RNA Processing
all take place within the _________.
NUCLEUS
A collection of similar cells that
work together to fulfill a certain purpose.
TISSUES
WHAT ARE THE VITAL FUNCTIONS PERFORMED BY A CELL?
Structure and support, Transport, Energy Production, Metabolism, Reproduction, Nutrition, Digestion, Absorption, Synthesis, Respiration, Excretion, Egestion, Secretion, Movement and Response
It is a function compared to a house made of bricks
STRUCTURE AND SUPPORT
Gives plants mechanical
support and elasticity
COLLENCHYMA
Supports plants
mechanical structure
SCLERENCHYMA
The cells import the nutrients that are used
in the different chemical processes which
take place inside them
TRANSPORT
The cells then work to get rid of this waste.
In this manner, small molecules such as
oxygen, carbon dioxide, and ethanol pass
through the cell membrane by diffusion. This
method is known a
PASSIVE TRANSPORT
go in and out of the cell via
ACTIVE TRANSPORT
organisms need energy to perform
different chemical reactions
ENERGY PRODUCTION
