Plants

Chlorophyll:A chemical that gives plants their green color and trops light energy.

Photosyntesis:The precess in which plants use water, carbon dioxide and energy from the sun to make food.

Vascular plant: plant that have tube-like cells,in their root, stems and leaves to carry food and water.

Non vascular plant:plant that don´t have tube-like cells in their stems and leaves.

Moss: a small non vascular plant  that have bouth;stems and leaves, but no roots.

Sexual Reproduction: the forming of a new organism with the union of two cells.

Egg:a female reproductive cell.

sperm: a male reproductive cell.

Fertilization:the joining of egg and sperm.

Xylem:cells that carry water and disolved minerals from the root to the leaves.

Pholem: cell that carry food that is made in the leave to all part of the plant.

 

Fern :Avascular plant that reproduce with spore.

Seed: a part of a plant that contains a new young plant and stores food.

Embryo: An organism in it earliest stagesof growth.

Conifer: A plant that reproduce seed in cones.

Pollen: the tiny yellow grain on seeds plants in which sperm develops.

Flowering  plant: A vascular plant that produce seeds inside a flower.

Flower:the reproductive part of a flowering plant.

 

Feature of life and the cell

reproduce:to form offsprings similar to the father.

development: all the changes that occur as a living thing grows up.

consumer:living things that eat,or consume,other livings things.

 

producer:living things that  make,or produce,theeir own food.

cellular respiration:the process by which food is broken dow and energy is released.

cell:the basic unit of all living things.

adaptation:a trait that  makkes a living thing better able to survive.

cell membrane:the cell part that gives the cell shape and hold the cytoplasm.

nucleous:the cell part that control most of the cell's activities.

nuclear membrane: a structure that suroounds the nucleous and separate its from the rest of the cell.

nucleolus: the cell part that helps make ribosomes.

chromosome: cell parts with information that determines what traits a living thing willl have.

cytopllasm: the clear,jellylike material between the cell membrane and the nucleous that makes up most of the cell.

ribosome: cell parts where proteins are made.

mithoccondria: cells parts that  prroduce energy from food that has been digested.

vacuolle: a liquid-filled space  that stores food,water and minerals.

centriole: cells parts that help with cell reproduction.

chloroplasts: cells parts that contains the green pigment ,chlorophyl.

cell wall: the thick, outer covering outside the cell membrane.

diffusion: the movement of a substance from where there is a large amount of it to where there is a small amount of it.

 osmosis: the movement of water across the cell membrane.

tissue: a group of similar cells that work together to carry out a special job.

organ: a group of tissues that work together to do a job.

organ system: a group of organs that  work together to do a certain job.

The Study of life

biology:The study of living and once-living thing

 light microscope:light passess through the object being lookes andthen through two or more lenses

  









stereomicroscope:use for viewing large objects and things through  wich light cannot pass.

 

Scientific Method: it is a series of steps used to solve problems

Hypothesis.A hypothesis is an statement that can be tasted

Experiment: Testing a hypothesis using a series  of steps with controlled conditions.

Internacional System of Units:a measuring system based on units of ten

meter: an SI unit of lenght

volume:The amount of space a subtance ocuppies 

Kilogram: an SI unit of mass

celsius: a scale with which scientist  measure temperature

variable:something that causes the changess observed in a experiment.

control: a standard for comparing results.

data: the recorded facts or measurements from an experiment.

theory: a hypothesis that has been tested again and again by many scientist,with similar results each time.

technology: the use of scientific discoveries to solve everyday problems.
