structure inside a cell; each has a specific function.
1 of 18
nucleus
a large, membrane bound organelle found in eukaryotic cells which contains the genetic material in the form of chromosomes.
2 of 18
mitochondrion
the organelle found in eukaryotic cells in which most of the ATP synthesis occurs; it is the site of aerobic respiration.
3 of 18
chloroplasts
an organelle found in plants which contains chlorophyll and is responsible for photosynthetic activity.
4 of 18
lysosomes
membrane bound vesicles made by pinching off from the Golgi body; they usually contain digestive enzymes.
5 of 18
ribosomes
the organelle, made from 2 subunits, on which proteins are synthesised inside the cell.
6 of 18
centrioles
an organelle from which the spindle fibres develop during cell division in animal cells.
7 of 18
nuclear envelope
the double membrane structure surrounding the nucleus in eukaryotic cells.
8 of 18
RNA (ribonucleic acid)
a single-stranded polynucleotide molecule that exists in three forms; each form plays a part in the synthesis of proteins within cells
9 of 18
cristae
the folds found in the inner membrane of a mitochondrion, covered with stalked particles containing ATP synthase.
10 of 18
matrix
the central part of the mitochondria.
11 of 18
thylakoids
flattened membrane sacs found in chloroplasts, which hold pigments used in photosynthesis and are the site of light-dependent reactions of photosynthesis.
12 of 18
enzymes
a protein molecule that acts as a biological catalyst.
13 of 18
mRNA (messenger RNA)
carries the information coding for a polypeptide from the nucleus to the ribosomes in the cytoplasm.
14 of 18
spindle
a structure consisting of protein fibres found in eukaryotic cells during cell division; chromosomes become attached to this at their centromeres.
15 of 18
stroma
the gel-like matrix found in chloroplasts; the membranes of the thylakoids are embedded in this.
16 of 18
granum
a stack of thylakoids
17 of 18
eukaryotic cell
cells that have a nucleus inside a nuclear envelope and other membrane-bound organelles
