What are two structures of a plant?

What is the smallest parts that make up an animal?
All living organisms, including plants, animals, bacteria and fungi, are made up of cells. Cells are the smallest parts of all living organisms.
What are the smallest living parts of plants and animals?

Is a plant made up of only one cell?
Plants, animals, fungi and protists are all eukaryotes; these organisms are made up of one or more cells with a variety of membrane-bound organelles, including the nucleus — the big boss organelle that contains all the DNA and all the instructions for making that particular bear or ringworm or ficus tree or fruit fly.
Which is the smallest and the largest plant cell?
Plant cell:- Smallest cell:-Duckweeds of the genus Wolffia are the world’s smallest flowering plants and measure only 300 µm by 600 µm and reach a mass of just 150 µg.The cells of this plant are smallest. Largest cell:- aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants.
What are the characteristics of a plant cell?
Structure and Characteristics of a Plant Cell. A model of a typical plant cell is found to be rectangular in shape, ranging in size from 10 to 100 µm. Under the microscope, it shows many different parts. Each part, known as an organelle, works together to keep the cell functional.
What makes up the outer layer of a plant cell?
It is the outermost, protective layer of a plant cell having a thickness of 20-80 nm. Cell walls are made up of carbohydrates such as cellulose, hemicellulose, and pectin and a complex organic polymer called lignin.
What are the largest and smallest organelles in a cell?
– The Handy Biology Answer Book What are the largest and smallest organelles in a cell? The largest organelle in a cell is the nucleus; the next largest would be the chloroplast— only found in plant cells—which is substantially larger than a mitochondrion.
