Sci- plants and cells 🤡 Flashcards
what is the stage on a microscope
this is a flat surface where the slide containing the specimen is placed
what is the base on a microscope
it supports the microscope and provides stablility
what does the diaphragm do
it is a dial you turn that controls the amount of light from the light source that reaches the specimen
what is the formula for magnification
size of image/size of real object
what are the seven life processes
- Movement
- Respiration
- Sensitivity
- Growth
- Reproduction
- Excretion
- Nutrition
how do you find the actual size of object
image/magnification
How do you find the size of image
magnification x actual size
what is a cell
the smallest structural and functional unit of all organisms
Name 3 parts of a plant cell
Nucleus- medium seed thing
mitochondrion- tiny seeds
cytoplasm- stuff that fills in the cell
What are the parts of a plant cell
cytoplasm- stuff that fills it it
cellulose cell wall- first line
cell membrane- second line
chloroplast- medium seed but smaller than nucleus thing
mitochondrion- tiny seeds
permanent vacuole- big seed
nucleus- medium seed
what are the parts of a animal cell
cytoplasm- stuff that fills it in
nucleus- medium seed
cell membrane- outer wall
mitochondrion- tiny seeds
what is a cell wall
a flexible or rigid boundary protecting a cell outisde the cell membrane
what is the nucleus
a membrane- bound structure inside eukaryotic cells that contain most of the genetic material
what is the cytoplasm
thick jelly like substance that fills all cells and is where most of the cellular reactions take place
what are the chloroplasts
found within plant cells, photosynthesis takes place here
what is the cell membrane
the barrier of the cell that controls what enters and exits the cell
what are vacuoles
a fluid-filled compartment inside a cell, surrounded by a membrane
what are the parts of an insect pollinated flower
- petal
- sepal- leaf
- receptacle- stem
stamen:male - filament- little string sticks
- anther- nut things on top of string sticks
Carpel: female - stigma- weird thing in middle (top of)
- style- stick under stigma
- ovary- egg circle under style
what is different in a wind pollinated flower
leaf thing is called palea
what does pollen contain
male sex cells
what do ovules contain
female sex cells (eggs)
word eqaution for photosynthesis
carbon dioxide+water—- sunlight/chlorophyl
—–> glucose +oxygen
what is photosynthesis
a chemical reaction that happens in living things like plants to give them nutrients. This happens when the plant or other living things are exposed to sunlight
LOOK AT Photosynthesis thing
DO IT 🤡
