What is the difference between root cells and leaf cells

The cell wall maintains the shape of a plant cell and provides protection. Cellulose is a major component of dietary fiber in the diets of animals. The cytoplasm is the internal space of a cell that is not filled by a nucleus or organelle. The endoplasmic reticulum is a network of membranes that are connected to the nucleus of a cell. Smooth ER does not have ribosomes through its membranes whereas rough ER does.

The endoplasmic reticulum is important for a number of cellular processes such as modifying and transporting proteins. Like the ER, the golgi apparatus is a network of membranes. It plays important roles in modifying proteins and lipids and moving substances out of the plant cell. Chloroplasts are a key feature of plant cells. Chloroplasts are green and are the reason why plants are typically green. Mitochondria are important organelles found in eukaryotic cells. They are the main site of cellular respiration — a process that converts the energy of sugars and other compounds into energy that cells are able to use.

Sugars produced by photosynthesis in chloroplasts are converted into usable cellular energy inside mitochondria. Ribosomes are small structures that are responsible for building new proteins. They can be embedded in the endoplasmic reticulum to form the rough ER or they can be floating in the cytoplasm of a cell. Ribosomes are one of the few structures found in both eukaryotic and prokaryotic cells. Vacuoles are another key feature of plant cells because they are not found in animal cells.

A vacuole is a large organelle that is mostly used for the storage and breakdown of different substances. Plant growth is often the result of increases in the size of vacuoles in plant cells. Peroxisomes are small organelles that perform a range of functions. They are known to produce hydrogen peroxide commonly used as bleach and convert it to water. The cells of plants and animals have some key differences. This is because plant cells contain chloroplasts but animal cells do not.

Plant cells also have a cell wall surrounding the plasma membrane and vacuoles inside. Root hair cells grow and reproduce more quickly than actual roots, which makes them great for biologists to study and learn about cell life. Their main very important! Sometimes, transferring a plant from one pot to another can cause the root hairs to fall from or get scraped from the plant.

Thankfully, though, root hairs grow quickly enough to repopulate and start to take in the nutrients from their new surroundings. Roots work to absorb whatever is around them. They take the nutrients from the surrounding soil that the plant needs to stay healthy, and they also absorb the water that gets into the soil either when people water the plants or through rainfall.

Roots can then either store those essential nutrients for later, or transport them to the stem of the plant. All in all, the roots might not be the prettiest part of any plant, but they help to provide the structure and nourishment that all plants need to stay healthy and alive. The upper part of the leaf is where the light falls, and it contains a type of cell called a palisade cell. This is adapted to absorb a lot of light. It has lots of chloroplasts and is shaped like a tall box.

Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata. Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or dry conditions. The lower part of the leaf is a spongy layer with loose-fitting cells. The palisade parenchyma layer is located just below the upper epidermal layer where sunlight is easily accessible to leaf cells.

Photosynthesis occurs in the heavily pigmented chloroplasts of the leaf cell, resulting in the production of energy-packed molecules of glucose, used as sugars or stored as starch. Spongy parenchyma is made up of irregular, lobe-shaped cells directly underneath the palisade parenchyma. The cells of this leafy tissue contain fewer chloroplasts, but photosynthesis does occur in both layers of the mesophyll.

Large intercellular air spaces in the spongy layer facilitate the exchange of oxygen and carbon dioxide entering and exiting the cell through the stomata.

The vascular bundle contains xylem and phloem tissues. Veins in the leaf are comprised of dead, tubular xylem cells that bring water to the leaf for use in photosynthesis.

Phloem moves sucrose and amino acids up and down from leaf to plant in a process called translocation. Mary Dowd studied biology in college where she worked as a lab assistant and tutored grateful students who didn't share her love of science. Her work history includes working as a naturalist in Minnesota and Wisconsin and presenting interactive science programs to groups of all ages.

She enjoys writing online articles sharing information about science and education. Currently, Dr.
