Eukaryotes also have several membrane-bound organelles. These membranes are similar to the cell membrane, which is a flexible film of lipid bilayers. Plant cells – Key similarities Animal cells and plant cells are eukaryotic cellsīoth animal and plant cells are classified as “ Eukaryotic cells,” meaning they possess a “true nucleus.” Compared to “ Prokaryotic cells,” such as bacteria or archaea, eukaryotic cells’ DNA is enclosed in a membrane-bound nucleus. Tree of living organisms showing the origins of eukaryotes and prokaryotes.Īnimal cells vs. Autotroph – can produce its own food using light, water, carbon dioxide, or other chemicals.Plants are multicellular organisms of the kingdom Plantae. Instead, taking nutrition from other sources Heterotroph – cannot produce its own food.Left: The compound microscope used by Robert Hooke to discover “cells.” Right: Cell structure of cork illuminated by Robert Hooke in Micrographia, 1665.ĭefinition: What are animals, and what are plants?Īnimals are multicellular organisms that form the biological kingdom Animalia. Tiny structural parts inside the cell, called organelles, are involved in various specialized functions to keep the cell alive and active. The word “cell” came from Latin, which means “small room.” The cell membrane encloses the content of the cell and separates all biological activities from the outside world.

The cell was first observed and discovered under a microscope by Robert Hooke in 1665. The cell is the basic unit or building block of living organisms.
