Blood cells – red, white blood cells and platelets floating in liquid plasma Standards  Human Cells and Its Function 2. Nerve cells – also called neuron.Cells with fiber which conduct impulses. It consist of a cell body, axon and dendrites. Standards  Human Cells and Its Function 3. Skeletal muscle cells – also called striated muscle cells because of their striped appearance when viewed under a compound microscope. Standards  Human Cells and Its Function 4. Ova or egg cells sex cells – Female sex cells produced by the ovaries. Standards  Human Cells and Its Function 5. Sperm cells –Male sex cells produced by the testes. Standards Kinds of Tissues in Animal Cells 1. Epithelial tissues. These are made up of closely-packed cells arranged in flat sheet. It forms lining of various cavities and tubes in the body such as lining of the small intestine which secretes digestive substances and absorbed products of digestion. This tissue is specialized to form the covering or lining of all internal and external body surface. Some has special functions of absorption, secretion, excretion, sensation and respiration. Standards Kinds of Tissues in Animal Cells Types of Epithelial Tissue Standards Kinds of Tissues in Animal Cells 2. Connective tissues hold parts of the body together, such as bones. The long tough fiber that hold bones onto other bones are called ligaments, forming joints, while the tissues which hold muscle to bone are called tendons. Cartilage is another type of connective tissue, which has widely spaced cells. Blood is regarded as specialized form of connective tissue because it originates in the bones and has some fibers. Standards Blood is composed of red blood cells, white blood cells and platelets. Kinds of Tissues in Animal Cells Standards Kinds of Tissues in Animal Cells 3. Muscle tissues are for movement in animals. a. Involuntary-muscles not under our conscious control. Example. The muscles in your stomach move even if we do not let them do so and the action cannot be stopped either. This type of muscle is also called visceral or smooth muscle. b.Standards Voluntary muscle – made up of long fibers and they move our bones. It is striated in appearance. We can control them at will. Example. We can raise our legs if we wish. This type of muscle is called skeletal muscle, since they are attached to the bones. c. Cardiac muscle is a special type of muscle that make up our heart. It is an involuntary muscle that is striated in appearance Kinds of Tissues in Animal Cells Standards Kinds of Tissues in Animal Cells 4 Types of neurons 1. Motor neurons/efferent a. Accept nerve impulses from the Central Nervous System b. Transmit them to muscles or glands 2. Sensory Neurons/ afferent a.Standards Accept impulse from sensory receptors b. Transmit them to CNS 3. Interneurons/association a. Convey nerve impulse between various parts of the CNS Kinds of Tissues in Animal Cells Standards  Plant Tissues A tissue is composed of a group of vegetative cells with one or more specific functions. 1. Meristematic tissues are tissues responsible to produce new cells. It is composed of immature cells and Standards regions of active in cell division. It have small, thin cell walls and rich in cytoplasm. Found in the growing tips of roots and stems  Plant Tissues Kinds of Meristems 1. Apical meristems. Found at the tips of stems and roots and are mainly responsible for the increase in length of stems and roots. Standards 2. Lateral meristems. Found in the sides or periphery of roots and stems. Responsible of the increase in width or diameter of stems or roots.  Plant Tissues A tissue is composed of a group of vegetative cells with one or more specific functions. 2. Permanent tissues. These are composed of mature and differentiated cells. Cells of this tissue Standards have lost their ability to divide, and they have specialized structure to perform specific functions. These are derived from meristematic tissues.  Plant Tissues Kinds of Permanent Tissues 1. Simple permanent tissue – consist of only one type of cells (eg. Parenchyma) 2.Standards Complex permanent – consist of more than one type of cells (eg. Xylem and phloem)  Plant Tissues Simple Permanent Tissues 1. Epidermis. This is an external tissue which consist of a single layer of living cells. It serves as the protective outer covering Standards of the leaves, young roots and young stems. It produce cutin to protect plants against loss of water.  Plant Tissues Simple Permanent Tissues 2. Parenchyma. This is an internal tissue and consist of living cells with thin cell wall. Found in the soft parts of roots, stems, leaves and flowers. Most of the chlorophyll of leaves are in the cells of parenchyma Standards tissue. It is where photosynthesis occurs. The functions of parenchyma of stems and roots is food manufacturing and food storage. Ex. Fleshy tissues of fruits and vegetables.  Plant Tissues Simple Permanent Tissues 2. Parenchyma. Standards  Plant Tissues Simple Permanent Tissues 3. Collenchyma. This is also an internal tissue. The collenchyma cells are structurally like parenchyma cells except that their walls are irregularly and compactly arranged. The collenchyma is a strengthening or supportive tissue and functions to store food. Standards  Plant Tissues Simple Permanent Tissues 3. Collenchyma. Standards  Plant Tissues Simple Permanent Tissues 4. Sclerenchyma. Also, an internal tissue consist of thick-walled, dead cells. The cells have uniformly thick heavily lignified secondary walls. They function mainly for support. Plant fibers are sclerenchyma cells. Found Standards also in stone cells of chico fruit and in seed coat of coconut shells.  Plant Tissues Simple Permanent Tissues 4. Sclerenchyma. Standards  Plant Tissues Complex Permanent Tissues Vascular Tissues 1. Xylem – primarily functions for the transport of water and dissolved substances upward in the plant body. 2.Standards Phloem – primary functions in the transport of organic material such as carbohydrates and amino acids.  Expand Long Quiz next Standards meeting
