Answer: takes time and energy

requires a mate

Sexual reproduction is a mode of reproduction in which two gametes of opposite sex fuse together to produce offsprings. The offsprings produce by this method are not genetically and physically identical to their parents. The sexual mode of reproduction brings variations among the organisms. The disadvantages of sexual reproduction are:

Takes time and energy: Compared to asexual mode of reproduction the sexual reproduction takes a long time. This is because of the fact that several organisms exhibit distinct mechanism for copulation which requires energy. Also, the gestation period in organisms is long and requires energy to produce offsprings.

Requires a mate: Sexual reproduction requires a mate because to produce offsprings the gametes from two opposite sex should fuse with each other. This is a disadvantage of sexual reproduction because of the fact that individuals have to find mates which is not an easy task, there is competition among the members of the same population to obtain mate, and there is danger of survival.

Morgarella [4.7K]

Answer:

you can see below

Explanation:

Basic Definitions:

Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere.

Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. Usually made up of cellulose and ONLY found in plant cells.

Nucleus = A really dense organelle of the cell usually surrounded by two membranes. They contain and protect your genetic material. Basically everything that makes you, you.

Cytoplasm = The watery, salty, and protein filled 'soup' that fills the cell. All organelles float happily in this.

Now Specific Locations:

Eukaryotic cells

have plasma membranes

please mark me brainliest or mark me thanks at leat

only have cell walls if the cells are plants.

They do have a nucleus.

They have cytoplasm

Prokaryotic cells

have plasma membranes

cell walls are usually chemically complexed.

don't have a nucleus

have cytoplasm

Animal cells

only have the plasma membranes.

No cell wall

have a nucleus

have cytoplasm

Plant cells

have both the cell wall

and have a plasma membrane
