Answer:
Easy.
1. The egg is made in the ovaries, and the sperm is made in the testes.
2.the egg goes down the fallopian tube and into the uterus, while the sperm goes upwards, they most often meet in the fallopian tube.
3.if the egg is not fertilized, the egg disintegrates and the body sheds the lining in the uterus, which results in your period.
Hope this is good!
Answer: Lysosomes synthesize proteins from the recycled amino acids.
Explanation:
This is a cell organelle with a spherical sac shape, bounded by a single membrane.( Unlike chloroplast and mitochondrial which double membranes.) It contain digestive enzymes which is hydrolytic in nature, this splits molecules by addition of water molecules. The digestive enzymes are separated from other cell organelles because of autolysis/autophagic which is automatic discharge of digestive enzymes in a contained cell which destroy the whole cell.
T<u>hey release vesicles containing the enzymes towards the target structure,and the vesicle fused with the membrane of the target cell to discharged the hydrolytic enzymes for digestion</u>
They breakdown old and worn out cells organelles, or the whole cell (for example the breakdown of mammary glands after lactation. Lysosomes are also used to digest bacterial in white blood cells by ENDOCYTOSIS.
Note: RIBOSOMES play a role in protein Synthesis not LYSOSOMES.
Their average size is 0.1-0.5µm in diameter
They have different specifications eg. a muscle cell has lots of mitochondria as it needs to do a lot of work, or a neuron has to have a mylin sheath to insulate signals
