Gen bio exam

• Tissue: is a group of cell with similar function
• Organs: are tissues with related functions
• Organ System: organs the work together to achieve a common function
• Organism: is made up of several organ system with different structures and specific function
• Dermal tissue system: is found in the outermost layer of the plant
• Cuticle: a waxy coat found in the leaves and stems
• Vascular tissue system: transport material between roots and shoot system
• Xylem: transports or moves water and minerals from the roots
• Phloem: transport or move sugar and nutrients
• Pith: is referred to as the tissue found inside the vascular system of a plant
• Cortex:is referred to as the tissue found outside the vascular system of a plant
• Endodermis: regulates the movement of molecules from the cortex to the vascular tissues
• Ground tissue system: is composed of tissues that are neither dermal nor vascular
• Epithelial tissue: is the outermost covering of the animal
• Connective tissue: this tissue is responsible for keeping tissues and organs together in place
• Muscle tissue: enable body movement and is responsible for muscle contractions
• Skeletal muscle tissue: found attaches to the bones and is responsible for voluntary movement
• Smooth muscle tissue: forms the walls of internal organs and function in involuntary body activities
• Cardiac muscle tissue: forms the walls of the heart, enabling nonstop muscle contractions
• Nervous tissue: functions mainly in information processing
• Nervous tissue is made up of neurons and glial cells
• Glial cells: nourish, insulate and replenish the neurons
• Neurons: are responsible for receiving and passing on the nerve impulses or messages
• Sexual reproduction: is the generation of genetically varied or different offsprings from two parents
• Asexual reproduction: occurs when a produced offspring is genetically identical to the sole parent
• Angiosperms: scientific name for flowering plants
• Four major parts of the flowering plants are sepals, petals, stamen, and carpel
• Sepal: serves to protect the flower
• Petals: attracts potential pollinators
• Stamens: contain the sperm of the flower
• Carpel: contains the egg cells of the flower
• Stamen consist of the anther and filament
• Anther: is where the sperm cell is produced through a special type of cell division called meiosis
• Carpel are made up of stigma, style, and ovary
• Stigma: is the part where pollen ends up
• Style: is the part that holds up the stigma
• Ovary: houses one or more ovules
• Pistil: is what you would refer if one or more carpel is present
• Fertilization: is the union of sperm and egg cells
• Pollen grains: are the plant male gametophytes
