Compounds that make up the cells and structures of organisms include proteins, lipids, carbohydrates, and nucleic acids. Proteins serve as enzymes and structural components, lipids provide energy storage and cell membrane formation, carbohydrates offer energy and support, and nucleic acids (DNA and RNA) store and transmit genetic information. Together, these macromolecules play crucial roles in cellular functions, metabolism, and overall organismal development.
Cells and other structures of organisms are primarily composed of macromolecules, including proteins, nucleic acids (DNA and RNA), lipids, and carbohydrates. Proteins serve as enzymes, structural components, and signaling molecules, while nucleic acids store and transmit genetic information. Lipids form cell membranes and store energy, and carbohydrates provide energy and structural support. Together, these compounds enable various biological functions essential for life.
Differentiated cells are specialized cells that have developed distinct structures and functions to perform specific tasks within an organism. These cells arise from stem cells and are found in multicellular organisms, including animals, plants, and fungi. Examples include muscle cells, nerve cells, and epithelial cells in animals, as well as xylem and phloem cells in plants. In contrast, unicellular organisms typically do not have differentiated cells, as each cell must carry out all life processes independently.
Multicellular organisms are made up of specialized cells organized into tissues, organs, and organ systems. These structures work together to carry out specific functions necessary for the survival of the organism.
Organisms are made up of structures called cells, which are the basic units of life. Cells have specific functions and work together to form tissues, organs, and organ systems that help the organism carry out its life processes. The organization of cells into different structures allows organisms to perform specialized functions that are necessary for survival.
Organisms need to carry out the process of respiration because the cells in the organisms break down simple food molecules and release their energy.
Enzymes are the compounds used in organisms to carry out chemical reactions and regulate metabolism. They act as biological catalysts to speed up reactions, allowing essential processes to occur efficiently within cells.
Cacti are multicellular organisms, as they are composed of many cells that work together to form the various tissues and structures of the plant. Cells in a cactus carry out different functions such as photosynthesis, water storage, and support.
Hemoglobin
These organisms are likely referring to cells. Cells use specialized organelles like mitochondria for energy production and the endoplasmic reticulum for protein synthesis to carry out the activities needed to maintain homeostasis. Specialized internal structures allow cells to perform specific functions efficiently.

organells
Yes.
Cells are the smallest structures that can perform all the activities required for life. They contain the necessary components such as DNA, cytoplasm, and organelles to carry out functions like metabolism, growth, and reproduction.

An acellular organism is one that lacks cells and is typically very simple in structure. These organisms, such as viruses and prions, do not have the typical organelles and structures found in cells. They also rely on host cells to replicate and carry out their biological functions.
