Explanation:
This is an animal cell because it is shown to be rounded or curved (whereas plant cells would have straight lines as the outer layer). Cells are made up of parts called organelles, which are what we are labelling.
A 1 Nucleus
The nucleus is the "control centre" of the cell and where DNA is stored. It is typically drawn to be round and having another circle inside it (nucleolus).
B 3 Rough Endoplasmic Reticulum
The Rough ER (for short) is part of the transport system of the cell. It has ribosomes unlike the smooth ER, which makes it "rough" (notice the small dots on the structure). Ribosomes are partially made in the rough ER.
C 9 Plasma Membrane
The plasma membrane is the outermost protection layer for the cell. It controls what comes in and goes out of the cell and also provides a structure. It may also be called the "semi-permeable membrane" because it only allows some substances to pass through it.
D 8 Cytoplasm
The arrow seems to be pointing to an empty space of purple, and this purple is found throughout the entire cell like a background. The cytoplasm suspends all other organelles, allows movement within the cell and provides structure.
E 5 Golgi apparatus
Also known as the "golgi body", its job is to package proteins and prepare them for transport. It often looks like a stack of something in side view.
F 6 Mitochondria
The mitochondria is the powerhouse of the cell because it's where cellular respiration happens (produces energy). It usually is drawn with squiggly lines inside an ovular shape.
G 2 Ribosome
Ribosomes is where protein synthesis happens. They are found all over the cell and are really small. They begin their journey in the nucleus, travel through the rough ER, are packaged in the golgi apparatus, then directed to where they are needed.
H 4 Smooth Endoplasmic Reticulum
The smooth ER (for short) is also a part of the transport system. Unlike the rough ER, it does not have ribosomes. Its jobs include regulating calcium levels and making lipids (fat).
I 7 Lysosome
Lysosomes are like Lysol (if this helps you remember). It does the "cleaning" in the cell. It has enzymes that digest dead organelles and food.
