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...
- Cell Wall. 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.
- Plastids. They are double membrane-bound organelles that have their own genetic material. Plastids are mainly of three types: a) Chloroplasts: Found in the green parts of a plant and algae that contain the photosynthetic pigment, chlorophyll.
- Central Vacuole. It is the large vesicle that make up almost 30 to 80% of the total plant cell volume. The central vacuole is often the largest organelle in the cell that is filled with fluid, ions, enzymes, and other molecules.
- Cell Membrane or Plasma Membrane. 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.
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.
Jan 15, 2021 · Plant and animal cells are both eukaryotic cells, meaning they possess a defined nucleus and membrane-bound organelles. They share many common features, such as a cell membrane, nucleus, mitochondria, Golgi apparatus, endoplasmic reticulum, ribosomes, and more.
Oct 21, 2024 · A plant cell is the basic unit of all plants. Plant cells, like animal cells, are eukaryotic, meaning they have a membrane-bound nucleus and organelles. Their characteristic cell wall is composed of cellulose, and they contain chloroplasts for photosynthesis.

Definition: Photosynthesis. Photosynthesis is the process that converts carbon dioxide and water into sugars such as glucose and oxygen in the presence of sunlight. Example 1: Recalling the Key Characteristics of Kingdom Plantae. The picture provided shows an organism belonging to the kingdom Plantae.
May 16, 2024 · The cell membrane, also known as the plasma membrane, is a thin, semi-permeable barrier that surrounds and encloses the contents of a cell. It separates the interior of the cell from the external environment, protecting the cell and regulating the movement of substances in and out of the cell.
