Cells to Body Systems
Similar cells working together form this.
A tissue
Bacteria belong to this cell type, which lacks a nucleus.
Prokaryotic
Specialized structures that work together inside a cell are called ________________.
Organelle
These tiny structures assemble proteins.
Ribosomes
This tissue covers and lines surfaces and can protect, secrete, and absorb.
Epithelial tissue
Different tissues working together form this.
An organ
Plant and animal cells both belong to this cell type.
Eukaryotic
These organelles produce most of the ATP used by most human cells.
Mitochondria
Some ribosomes are attached to ____________.
Rough endoplasmic reticulum
This tissue is made of cells that contract together to produce movement.
Muscle tissue.
Put these in order from simplest to most complex: tissue, organism, cell, organ system, organ.
Cell → tissue → organ → organ system → organism
A plant cell has these two structures that animal cells lack.
A cell wall and chloroplasts
Mitochondria use _______________ to produce energy called APT.
Glucose or molecules from food
______________ helps fold and transport proteins made by its attached ribosomes.
rough endoplasmic reticulum (rough ER)
A root hair cell absorbs water, while a sperm cell moves toward an egg. Their different structures support different __________.
Functions
The kidney contains several tissues. The urinary system contains several organs. Which has the higher level of organization?
The urinary system
A yeast organism consists of one cell with a nucleus. Classify it using both cell type and number of cells.
Eukaryotic and unicellular
The nuclear membrane allows every molecule to pass freely.
True or false
False
This organelle modifies, sorts, and packages proteins for delivery.
Golgi apparatus
Unspecialized cells become specialized cells through this process.
Cell differentiation
A sunflower and a single-celled alga both carry out life processes. Which has more levels of structural organization?
The sunflower
Eukaryotic organisms can be ONLY multicellular.
True or False
False
A chemical stops mitochondria from functioning. Name the immediate change in the cell’s supply of usable energy.
ATP production decreases
A vesicle carries proteins to the cell’s outer boundary, where they are released outside. What structure forms this boundary?
Cell membrane
Cell differentiation is important in multicellular organisms. Explain why?
Because it creates cell that are specialized for performing specific jobs.
