Long Life Eggs

Oocytes [egg cells] – with a female mammal from birth – provide cytoplasm for a resulting embryo so must be maintained in good condition over a long time. This study shows how potentially damaging protein aggregates are stored for degradation in 'compartments' (vesicle assemblies) in the oocyte

For example this is the diagram you have to learn so you can learn it like-

Each cell has a protective outer layer (plasma membrane) , so the cell only lets some certain things or nutrients into the system that it needs but keeps other things out (semipermeable).

Inside the animal cell there is the digestive system (cytoplasm), in the digestive system there is the working organs (organelles).

Tiny grains floating inside the system are called (ribosome) where protein is made.

The cell also has a DNA (nucleus) that contains all are genetic information the DNA is found on structures of the cell (nucleus) called chromosomes .

The nucleus is surrounded by a layer or cover (nuclear membrane) which controls what goes in and out.

Rough ER is a series of folded protective outer layer (membrane) rough ER is always spotted with the tiny grains floating around the system (ribosomes). Together the ribosomes and rough ER make new proteins and protective layer (membranes) that the system or cell needs.

While smooth ER is the opposite, it has vehicles which are used to move things around the digestive system (transport vesicles).

Now there is another working organ which helps in packaging up things, to be transported around cells or need to leave the cell like hormones (Golgi Apparatus).

Now comes lysosomes, lysosomes are both the vitamin c and the decomposer of the cell. It kills the bacteria that invades the body and it also break downs the THINGS that cell doesn 't need.

Vacuoles are large membranous sacs used to store things. While vesicles are smaller sacs.

Mitochondria is the powerhouse that breaks down sugar (ATP) which helps the cell get energy .

“Without it, there is nothing.”

Here's one of my new Drawtumn sketches with some digital color - it's the li'l slime gal, Morgan Elle! I went a slightly unconventional route and based her on a cell, with ribosome freckles, endoplasmic reticulum locks of hair, a mitochondria heart, and a cell wall outfit!

I'm rather pleased with how the colors turned out. The effect makes me think of the translucent, squishy material those "sticky hand" toys are made of. XD
