what is a cell?
the smallest unit that can perform all life processes.
what is cell theory? cell theory has 3 parts
part 1, all organisms are made of one or more cells.
part 2, the cell is the basic unit of all living things.
part 3, all cells come from existing cells.
what are the parts of a cell called? organelles
structures that perform specific functions within the cell.
what are the organelles in a cell? nucleus
contains the cells DNA. city hall.
what are the organelles in a cell? cell membrane
the barrier between the inside of a cell and the cells environment. city limits.
what are the organelles in a cell? cell wall
a ridge stricter that surrounds the cell membrane and provides support for the cell. found in plant cells only. city wall.
what are the organelles in a cell? chloroplast
organelles in a plant or Aggie in which photosynthesis takes lase. soler energy plants.
what are the organelles in a cell? mitochondria
the site of cellular respiration.
what are the organelles in a cell? ribosome
organelles that make proteins which are building materials for the cell. lumber yard.
what are the organelles in a cell? endopamic reticulum
allows for the trans port of cellular materials. roads and highways.
what are the organelles in a cell? Golgi complex
packages materials to be transport the cell. post office.
what are the organelles in a cell? vacuoles
stores water in the cell. water tower.
what are the organelles in a cell? cytoplasm

what is Mitochondria / Mitochondrion?
Mitochondria are membrane bound cell organelles.
what is Chloroplast?
a plastid that contains chlorophyll and in which photosynthesis takes place.
what is Vacuole?
a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
what is Prokaryote?
a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles.
what is Eukaryote?
any cell or organism that possesses a clearly defined nucleus.
what is Tissue?
Tissue is a group of cells that have similar structure and that function together as a unit.
what is Organ?
a part of an organism that is typically self-contained and has a specific vital function, such as the heart or liver in human
what is Organ system?
An organ system is a biological system consisting of a group of organs that work together to perform one or more functions.
what is Organism?
the material structure of an individual life form.
what is Structure.
the arrangement of and relations between the parts or elements of something complex.
