What is a cell?
The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.
What is a nucleus?
A nucleus, as related to genomics, is the membrane-enclosed organelle within a cell that contains the chromosomes
What is cytoplasm?
a fluid that fills the cell and occurs between the plasma membrane and the nucleus.
What is a cell membrane?
found in all cells and separates the interior of the cell from the outside environment.
What is a cell wall?
The cell wall is the protective, semi-permeable outer layer of a plant cell.
Mitochondria / Mitochondrion
They generate the cells energy needed to power the biochemical reactions.
What is Chloroplast
in green plant cells a plastid that contains chlorophyll and in which photosynthesis takes place.
Golgi complex
A stack of small flat sacs formed by membranes inside the cell’s cytoplasm gel like fluid.
what is endoplasmic reticulum
a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached.
what is ribosome
a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells.
what is Vacuole
a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
what is Organelle
Any of a number of organized or specialized structures within a living cell.
What is Prokaryote
Any organism that lacks a distinct nucleus and other organelles due to the lack of internal membranes.
What is a Eukaryote
An organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes
what is Tissue
Types of material of which animals or plants are made of.
what is an Organ
part of an organism that is typically self contained and has a specific vital function like the heart or liver in humans.
what is an Organ system
A group of organs that work together in the body to perform all sorts of functions.
what is an Organism
An individual animal, plant, or single celled life form.
what is a Structure
It is Anything made up of parts held together.
What is Lysosome
An organelle in the cytoplasm of eukaryotic cells.
