Structural features that contain the protein actin and help to control the shapes of cells are?
Structural features that contain the protein actin and help to control the shapes of cells are actin filaments, also known as microfilaments. These filaments are part of the cytoskeleton and play a key role in cell shape maintenance, cell movement, and cell division. They can assemble and disassemble rapidly to alter cell shape as needed.
What structural feature on the surface of a plasma membrane allows cells to recognize one another?
Glycoproteins and glycolipids are structural features on the surface of the plasma membrane that allow cells to recognize one another. These molecules can act as cell identifiers by creating unique patterns that other cells can identify and respond to.
Is the hollow cylinder that supports and shapes cells called a cell wall?
No, the hollow cylinder that supports and shapes cells is called the cell membrane. The cell wall is a rigid structure found outside the cell membrane in plant cells, fungi, and some bacteria, providing structural support and protection.
What is the smallest units or building blocks of all living things?
The smallest units or building blocks of all living things are cells. Cells are the basic structural and functional units of life and come in many different shapes and sizes depending on the organism.
What are lignified cells?
Lignified cells are specialized plant cells that have been strengthened by the deposition of lignin, a complex polymer that provides structural support and rigidity to the plant. These cells are important for structural support in plants, particularly in woody tissues such as stems and branches.

How do the differences in cell structures affect how plants and animals function?
The differences in cell structures between plants and animals significantly influence their functions. Plant cells have rigid cell walls and chloroplasts for photosynthesis, enabling them to synthesize their own food and maintain structural integrity. In contrast, animal cells lack these features and instead have flexible membranes, allowing for a greater variety of shapes and more complex movements. This structural variation supports different life strategies: plants primarily focus on growth and energy capture, while animals are adapted for mobility and interaction with their environment.

How do plant cells have different shapes?
To perform different functions plant cells assume different shapes
What features are common to eukaryotic cells?
Some common features of eukaryotic cells include membrane-bound organelles, a nucleus that houses DNA, cytoskeleton for structural support and movement, and the ability to undergo mitosis or meiosis for cell division.

What do cells do for the organism?
Cells are the basic structural and functional unit of an organism.
Biological activities that occur within the cells of organisms give rise to various .?
hydrocarbon chain shapes
How are cells in a plant have different shapes and different jobs?
Plant cells have diverse shapes and functions due to their specialized structures that enable them to perform specific roles. For instance, parenchyma cells, which store nutrients, have a rounded shape, while xylem cells are elongated to facilitate water transport. Additionally, the presence of rigid cell walls, chloroplasts in photosynthetic cells, and various types of vacuoles contribute to their distinct forms and functions, allowing plants to efficiently carry out processes like photosynthesis, nutrient storage, and structural support.
