|---|---|---|---|---|---|
| What is Osmosis? | Special type of diffusion that only involves the movement of water through a selective permeable membrane.
🗑
|
||||
| What is Diffusion | Diffusion is the movement of particles from an area where there are many of them to an area where there is few of them.
🗑
|
||||
| What is cellular transport? | Cellular transport is how materials move in and out of cells
🗑
|
||||
| What is permeability? | Permeability is how easily materials move in and out of cells
🗑
|
||||
| What is a Unicellular Organism? | a unicellular organisms are living things that are made from a single type of cell
🗑
|
||||
| Where can Unicellular Organism be found? | They can be found anywhere that can sustain life;for example soil or water
🗑
|
||||
| What are Phytoplankton? | Phytoplankton are unicellular organism that live in the ocean and use the process photosynthesis to convert the suns energy into sugar (food). they are important because they supply most of the earths oxygen.
🗑
|
||||
| How are bacteria essential for life on earth? | Good bacteria completes the cycle of matter by taking nitrogen and turning it into soil for plants to live
🗑
|
||||
| Name three types of microscopic unicellular organisms. | Diatoms, Paramecia, E. coli
🗑
|
||||
| How are diatoms like plants? | Diatoms are like plants because, both plants and diatoms use the process photosynthesis to make their own food using the sun’s energy .
🗑
|
||||
| What basic activities do unicellular organisms preform that are the same as complex plant and animal organisms ? | The same basic activities that both unicellular organisms perform and complex plant and animal organisms are that they all move, eat, respond to stimuli, reproduce, and expel waste from cellular activities.
🗑
|
||||
| How do Paramecia move? | They have little hairs called cilia which act like little oars and propel the organism along
🗑
|
||||
| In what environments can amoebas be found? | They are often found in a water based environment both fresh and saltwater
in wet decaying vegetation on the forest floor
in wet soil
and in other living organisms
🗑
|
||||
| Does an amoeba have a cell membrane? | yes
🗑
|
||||
| What commonly visible organelles do amoebas have? | nuclei, cytoplasm, food vacuoles, and a special vacuole that pumps water out of the cell to prevent it from bursting
🗑
|
||||
| How does water enter an amoeba? | Water enters by osmosis
🗑
|
||||
| What diffuses into and out of the amoeba? | Oxygen diffuses into the organism and carbon dioxide waste diffuses out of the organism
🗑
|
||||
| Are amoebas carnivores, herbivores or omnivores? | They can be carnivores herbivore or omnivores
🗑
|
||||
| what common foods do amoebas eat? | They commonly eat algae and bacteria
🗑
|
||||
| What are amobeas hunting skills based on? | they change shape to hunt
🗑
|
||||
| How do amoebas digest and eliminate their food? | Chemicals called enzymes digest the food, the nutrients are absorbed by the organism, and the vacuole disappears.
🗑
|
||||
| Draw picture of a moving amoeba | refer to your sheet
🗑
|
||||
| How is a multi cellular organism different than an unicellular organism? | A multicellular organism is made out of at least 2 different types cells, but a unicellular organism is made out of only one type of cell
🗑
|
||||
| What are specialized cells? | Specialized cells perform specific functions, such as digestion or movement. They must interact with other types of cells in the organism in order to carry out their tasks successfully
🗑
|
||||
| Why are Unicellular organisms usually micro-sized? How does this effect the process of osmosis and diffusion? | Unicellular organisms are usually micro-sized because cellular activities are performed most efficiently at that size. Diffusion and osmosis are only effective across very short distances.
🗑
|
||||
| Why do larger things tend to be made from many different cells rather than one huge cell? | When you have a bunch of small cells, diffusion and osmosis can happen at fractions of a second. if it is one big cell it takes a lot longer for diffusion and osmosis to occur
🗑
|
||||
| Why is it so important to have specialized cells in a multi cellular organism? | Multicellular organisms can be seen as a small community, everything has a job (specialized cells) if no one does their job than the community will fail and nothing would be able to grow or develop.
🗑
|
||||
| Name an example of an multi cellular organism. | an hydra
🗑
|
||||
| What do skin cells do in a human body? | Protection and gatekeepers
🗑
|
||||
| What do digestion cells do in a human body? | Breaking down food in body for nourishment
🗑
|
||||
| What do muscle cells do in the human body? | Converting lots of energy
🗑
|
||||
| What do bone cells do in the human body? | makes up the structure that supports the body
🗑
|
||||
| What do nerves/brain cells do in the human body? | Transmitting electrical impulses
🗑
|
||||
| What do eye cells do in the human body? | detect light
🗑
|
||||
| What do blood cells do in the human body? | Transport oxygen and carry away wastes of cellular process
🗑
|
||||
| What do storage cells do in the human body? | Keep unused energy on hand in the form of fat, to be released and burned when the need arises
🗑
|
||||
| What do leaves do in plants? | Transform suns energy into sugar
🗑
|
||||
| what does the stem do in plants | Store food, support plant, and transport food and water
🗑
|
||||
| What do the roots do in plants? | Store food, absorb water from plant, and transport water and nutrients to stem
🗑
|
||||
| How does E. coli move? | They move by a rotating flagellum that looks a bit like a tail, these organelles "swim" to move around
🗑
|
||||
| How do amoeba move? | These organelles move around by changing shape forcing its cytoplasm into extensions called pseudopods
🗑
|
||||
| Why are phytoplankton essential to life on earth? | They provide most of the oxygen in the earths atmosphere and they are the start of the oceans food chain.
🗑
