Question

I WILL GIVE YOU BRAINLYEST!! What gives a plant cell structure?

Answer 1

Answer:

The cell was first discovered in 1665 by an English scientist named Robert Hooke. While looking through a microscope, he observed tiny box-like objects in a slice of cork (bark from an oak tree) and named these boxes cells. Cells are the basic units of life, which make up all living things. This idea forms the basis of the Cell Theory. Plant cells are larger because they contain all of these structures but have some unique structures like a cell wall, vacuole and chloroplasts.

All these specialised structures are called organelles. An organelle is a tiny structure inside an animal or plant cell that has a specific function or role.

Answer 2

Answer:

The cell wall provides strength and support to the plant, much like the exoskeleton of an insect or spider (our skeleton is on the inside of our body, rather than on the outside like insects or spiders).

The plant cell wall is mainly made up of the carbohydrates molecules cellulose and lignin. Cellulose is used extensively by humans for making paper. Cellulose can also be converted into cellulosic ethanol, a type of biofuel. Some animals, such as cows, sheep and goats, can digest cellulose with the help of bacteria in their stomachs. Humans cannot digest cellulose, which passes through our bodies and is better known as dietary fiber, something that we should eat to keep our waste moving as it should! Lignin fills in the spaces between cellulose and other molecules in the cell wall. Lignin also helps water molecules move from one side of the cell wall to the other – an important function in plants.
