The following are examples of structures and organelles that can be found in typical animal cells:
* Centrioles – organize the assembly of microtubules during cell division.
* Cytoplasm – gel-like substance within the cell.
* Endoplasmic Reticulum – extensive network of membranes composed of both regions with ribosomes (rough ER) and regions without ribosomes (smooth ER).
* Golgi Complex – responsible for manufacturing, storing and shipping certain cellular products.
* Lysosomes – sacs of enzymes that digest cellular macromolecules such as nucleic acids.
* Microtubules – hollow rods that function primarily to help support and shape the cell.
* Mitochondria – power producers and the sites of cellular respiration.
* Nucleus – membrane bound structure that contains the cell’s hereditary information. * Nucleolus – structure within the nucleus that helps in the synthesis of ribosomes.
* Nucleopore – tiny hole within the nuclear membrane that allows nucleic acids and proteins to move into and out of the nucleus. * Ribosomes – consisting of RNA and proteins, ribosomes are responsible for protein assembly.

The Essay on Cell Structure And Function 2
... Plant Cell: Nucleus, cell wall, plasma membrane, cytoplasm, chloroplast, mitochondria, vacuoles Animal Cell: Nucleus, nucleolus, plasma membrane, cytoplasm, mitochondria, golgi apparatus, rough ER, ribosome Questions 1. For each structure ... types of cells are covered by a cell membrane and are made of the same basic chemicals: proteins, fats, minerals, and carbohydrates. Ribosomes are responsible ...
* Cell (Plasma) Membrane – a thin, semi-permeable membrane that surrounds the cytoplasm of a cell, enclosing its contents.
* Cell Wall – outer covering of the cell that protects the plant cell and gives it shape.
* Chloroplasts – the sites of photosynthesis in a plant cell. They contain chlorophyll, a green pigment that absorbs energy from sunlight.
* Cytoplasm – gel-like substance within the cell membrane containing water, enzymes, salts, organelles, and various organic molecules.
* Cytoskeleton – a network of fibers throughout the cytoplasm that helps the cell maintain its shape and gives support to the cell.
* Endoplasmic Reticulum (ER) – extensive network of membranes composed of both regions with ribosomes (rough ER) and regions without ribosomes (smooth ER).
* Golgi Complex – responsible for manufacturing, storing and shipping certain cellular products.
* Microtubules – hollow rods that function primarily to help support and shape the cell.
* Mitochondria – this organelle generates energy for the cell.
* Nucleus – membrane bound structure that contains the cell’s hereditary information. * Nucleolus – structure within the nucleus that helps in the synthesis of ribosomes.
* Nucleopore – tiny hole within the nuclear membrane that allows nucleic acids and proteinsto move into and out of the nucleus. * Peroxisomes – tiny structures bound by a single membrane that contain enzymes that produce hydrogen peroxide as a by-product. These structures are involved in plant processes such as photorespiration.
* Plasmodesmata – pores or channels between plant cell walls that allow molecules and communication signals to pass between individual plant cells.
* Ribosomes – consisting of RNA and proteins, ribosomes are responsible for protein assembly.
The Essay on Plant and Animal Structure
Duckweeds belong to a family of hydrophytic (aquatic) plants called Lemnaceae and are considered the smallest flowering plants. These plants lack the recognizable stems and leaves and they are instead characterized by several small flattened floating structures, which are believed to be modified leaves, often called as thalloids, with simple or no roots. Duckweed roots do not exhibit secondary ...
* Vacuole – structure in a plant cell that provides support and participates in a variety of cellular functions including storage, detoxification, protection, and growth. When a plant cell matures, it typically contains one large liquid-filled vacuole.
