Classification Review

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers, such as bacteria and fungi, break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What are the main characteristics of organisms in the kingdom Plantae?

Back

Organisms in the kingdom Plantae are multicellular, eukaryotic, and autotrophic, meaning they can produce their own food through photosynthesis.

Front

What does the endosymbiotic theory explain?

Back

The endosymbiotic theory suggests that early eukaryotic cells evolved from prokaryotic cells that formed symbiotic relationships by engulfing smaller bacteria.

Front

What defines organisms in the kingdom Animalia?

Back

Organisms in the kingdom Animalia are multicellular, eukaryotic, and heterotrophic, meaning they obtain their food by consuming other organisms.

Front

What is a key feature of eukaryotic cells?

Back

Eukaryotic cells have membrane-bound organelles, including a nucleus, which distinguishes them from prokaryotic cells.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs obtain food by consuming other organisms (e.g., animals).

Front

What are prokaryotic cells?

Back

Prokaryotic cells are unicellular organisms that lack a nucleus and membrane-bound organelles, such as bacteria.

Front

What is the significance of cell walls in plants?

Back

Cell walls, made of cellulose, provide structural support and protection to plant cells.

Front

How do fungi obtain nutrients?

Back

Fungi are heterotrophic organisms that absorb nutrients from their environment by breaking down organic matter.

Front

What is the primary function of bacteria in ecosystems?

Back

Bacteria play crucial roles as decomposers, breaking down dead material and recycling nutrients.
