Cell / Plant Parts
Explain how the Nucleus, Endoplasmic Reticulum, and Golgi Apparatus work together?
The nucleus sending instructions to the endoplasmic reticulum, which produces proteins that are packaged by the Golgi apparatus for export or use.
Why is the nucleus considered the "control center" of the cell?
It houses DNA, which contains the master instructions (blueprints) for the cell to make proteins.
How do different specialized cells work together to support the life and function of a multicellular organism?
Multi-cellar organisms are teams of different cells with specialized jobs?
Your body is organized like a building. If "cells" are the individual bricks, how do they eventually form a complex structure like the heart or the stomach?
Groups of similar cells work together to form tissues (such as muscle tissue or nervous tissue). Then, different types of tissues—like muscle, connective, and epithelial tissue—combine and cooperate to form an organ, allowing it to perform a complex job that a single cell couldn't do alone.
What specific molecule inside the nucleus holds the instructions to make proteins?
DNA
What is the difference between multicellular cells and single cells organisms?
One tiny cell does everything by itself, but a big team of cells works together to keep things running.
How is the human body built up from tiny parts into one person?
Through cell division.
How does every part of a cell work together like a team to get a specific job done?
A cell is like a team where every part does a small job so the whole group can finish one big task.
How do you know all living things are made of cells?
Cell Theory
If the cell membrane is like a security guard checking IDs at a door, how is the cell wall’s role in protection different?
It keeps the cell together and plant.
How do the mitochondria provide energy for the cell?
Each pair of electrons donated by the NADH produced in mitochondria is thought to provide energy for the formation of about 2.5 molecules of ATP.
Question: When a person starts running, how do the muscular and respiratory systems work together to help the body keep moving?
Answer: The muscular system needs more oxygen to power the muscles during exercise. The respiratory system responds by increasing the breathing rate to bring in more oxygen and exhale carbon dioxide. This evidence shows that without the respiratory system providing gas exchange, the muscular system would not have the fuel needed to function.
How do the chloroplasts provide energy for the cell?
By means of photosynthesis that capture the electrons that are excited when sunlight is absorbed by chlorophyll molecules.
