- Plant cells are the basic unit and building blocks of life in organisms of the kingdom Plantae. They are cells that have a distinct nucleus and other cellular organelles enclosed within a membrane and thus are eukaryotic in origin.

Mar 5, 2020 · 1. Non-Vascular Plants: Plants in this group live in moist environments because they cannot adapt to land environment. There are no real roots, stems, leaves and transmission bundles. They get the water they need directly from the environment by diffusion. They can reproduce both sexually and asexually.
Kingdom: Animalia: Cells have nuclei and no cell wall. Phylum: Chordata: Have backbones. Class: Mammalia: Have hair and produce milk for young. Order: Primates: Have flat faces, forward facing...

It is the outermost, protective layer of a plant cell having a thickness of 20-80 nm. Cell walls are made up of carbohydrates such as cellulose, hemicellulose, and pectin and a complex organic polymer called lignin.
They are double membrane-bound organelles that have their own genetic material. Plastidsare mainly of three types: a) Chloroplasts: Found in the green parts of a plantand algae that contain the photosynthetic pigment, chlorophyll. b) Leucoplasts: Found in the non-photosynthetic tissues of plants. c) Chromoplasts: Colored plastics found in fruits an...
It is the large vesicle that make up almost 30 to 80% of the total plant cell volume. The central vacuoleis often the largest organelle in the cell that is filled with fluid, ions, enzymes, and other molecules. Apart from plants, they are also present in algae.
It is a thin, biological membrane having a thickness of 7.5-10 nm that separates the interior of the cell from the outside environment. The plasma membrane is selectively permeable in nature, which is mainly composed of lipids and proteins, with some carbohydrates attached to them.
It is a series of membranes within the cytoplasm that forms connections with the nucleus on one side and cell membrane on the other. It is of two types: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The surface of RER has ribosomesattached to it, while they are absent in SER.
Also known as Golgi body or Golgi complex, they are stacks of five to eight membrane-covered sacs called cisternae. The Golgi apparatus acts as the post office of the cell by packaging and transporting proteins from their source RER to their destination.The number of Golgi apparatus varies in cells according to their functions.
They are a network of long and thin protein fibers present in the cytoplasm of the cell having a diameter of 3-6 nm. Microfilamentsare composed of actin proteins that make them extremely strong and flexible.
They are fibrous hollow rods composed of proteins called tubulin. Microtubuleshave an outer diameter of 23-27 nm and an inner diameter of about 11-15 nm. They can grow to as long as 50 µm and thus are highly dynamic.
They are made up of two proteins forming a coiled-coil structure. Intermediate filaments have a diameter of 8-10 nm that are intermediate in size to microfilaments and microtubules. Microtubules, together with microfilaments and intermediate filaments, form the cytoskeletonof the cell.
It is a rod-shaped double membrane-bound organelle that contains its own DNA and ribosomes. Mitochondria are often called the ‘powerhouse of the cell‘, producing ATP that drives all cell-based metabolic activities.
Contains genetic material, including DNA, which controls the cell’s activities. Cell membrane : Its structure is permeable to some substances but not to others.
Specialised plant cells have components that allow them to complete a specific purpose. Specialised plant cells include root hair cells, palisade cells, xylem cells and phloem cells.
Sep 4, 2018 · The plant kingdom has the following characteristic features: They are non-motile. They make their own food and hence are called autotrophs. They reproduce asexually by vegetative propagation or sexually. These are multicellular eukaryotes. The plant cell contains the outer cell wall and a large central vacuole.
Central Vacuole. Most mature plant cells have a central vacuole that occupies more than 30% of the cell's volume, but can also occupy as much as 90% of the volume of certain cells. The central vacuole is surrounded by a membrane called the tonoplast. The central vacuole has many functions.
