science
what is nucleus
the nucleus is the control center of the cell. the nucleus stores dna and genetic information required for mitosis and growth
what is nucleolus
the nucleolus is contained within the nucleus and is responsible for making ribosomes
ribosomes
ribosomes are the smallest membrane in the cell and creates protein. they are often referred to as protein factories
Golgi apparatus
the Golgi apparatus sorts important proteins and fat in the cell before they are delivered to their next destination
endoplasmic reticulum
is an anetwork of bubbles and tubes that are either rough or smooth. it helps modify and transport proteins
cell membrane
cell membrane is a barrier around the cell. it is semi-permeable, meaning that it allows something to enter the cell while other things are excluded. the role of the cell membrane is to control the entry and exit of various substances in the cell
lysosomes
lysosomes contain digestive enzymes for the cell
animal cell- vacuole
vacuoles are found in many small storage bubbles in an animal cell. they store food and nutrients in a cell
mitochondria
the mitochondria produce energy necessary for the cells to survive and function. the energy is converted from glucose into adenosine triphosphate-atp which is usable energy
cytoplasm
cytoplasm provides support for the internal structures of the cell. it contains the cells organelles
organells
the components in cells
cell wall
the cell wall is the rigid layer with the primary purpose of protecting and providing support for the cell
chloroplast
chloroplast contain chlorophyll which is required for photopsinthesis
vacuole- plant cell
vacuole is a large membrane in the cell that is filled with fluid that helps maintain the shape of the cell

what is a unicellular cell
a unicellular organism is a single cell that carries out all the necessary functions required for survival.
what is a multicellular cel
a cell made up of many cells that takes on specialized funtionns
what shape do plant cells tend to be
rectangular
what shape do animal cells tend to be
round or oval
eukaryotic
has a membrane bound nucleus
prokaryotic stands for
before nucleus
eukaryotic stands for
true nucleus
