Cell membrane ; Function: Its structure is permeable to some substances but not to others. It therefore controls the movement of substances in and out of the cell.

Plant cells are eukaryotic. In other words, each cell has a true nucleus and membrane-bound organelles. However, plant cells have characteristics that distinguish them from other eukaryotic cells: Cell Wall: Unlike animal cells, plant cells have a rigid cell wall outside the plasma membrane. This cell wall is primarily composed of cellulose, a comp...
Plant cells comprise several organelles, each with unique functions vital to the cell’s operation: 1. Cell Wall:The cell wall is a rigid layer that provides support, protection, and shape to the cell. It consists mainly of cellulose. 2. Plasma Membrane:This is a semi-permeable membrane that controls the movement of substances in and out of the cell...
While most people know plants cells contain chloroplasts, they may not realize there are other types of plastids in cells. Plastids are a group of plant cell organelles that perform a variety of essential functions. Like mitochondria, plastids have a double-membrane envelope and their own DNA and ribosomes. Here are some key plastids: 1. Chloroplas...
While plant and animal cells share many similarities as eukaryotes, they also exhibit notable differences: Cell Wall:Unlike plant cells, animal cells do not have a cell wall. This absence gives animal cells a flexible shape, allowing them to form structures such as neurons and muscle cells. Vacuoles:Animal cells contain smaller vacuoles and often m...
While plant cells are eukaryotic, bacterial cells are prokaryotic. This leads to several key differences between the celltypes: 1. Nucleus:Plant cells have a well-defined nucleus that houses their DNA. In contrast, bacterial cells do not contain a nucleus. Instead, their DNA is in a region called the nucleoid. 2. Size:Plant cells are generally much...
While both plant and fungal cells are eukaryotic, there are several key differences between them: 1. Cell Wall:The cell walls of plant cells contain cellulose, while fungal cell walls mainly consist of chitin. 2. Nutrition:Plant cells are autotrophic and produce their own food via photosynthesis. Fungal cells, on the other hand, are heterotrophic a...
There are different types of plant cells, each with specific structures and functions. These cells further organize into tissues that perform coordinated functions. 1. Parenchyma Cells:These are the most common type of plant cell. They are involved in many functions such as photosynthesis, storage, and tissue repair. Parenchyma cells typically have...
There are three main types of differentiated plant tissue, plus there is undifferentiated tissue: 1. Dermal Tissue:This is the outermost layer of the plant (the “skin”), which serves as a protective layer. It includes epidermal cells, guard cells (which regulate the opening and closing of stomata for gas exchange), and in some cases, specialized ce...
