- 15. The embryo of a plant’ also kernels of corn, wheat, etc., which botanically are seedlike fruits, including the ovary wall.
- 17. To develop into a plant from a seed, spore, or bulb.
- 19. Any matter, defined as organic incorporated in or on the surface of the soil. It may include undecomposed plant matter and highly humidified—sometimes used interchangeably with humus.
- 21. a group of textural classes in which the particles are finer than gravel but coarser than silt
- 23. is a mixture of minerals and organic material that covers much of Earth’s surface.
- 24. A mineral, or minerals, classified with the micas, expands into scales and becomes a loose, absorbent mass with treatment at high temperatures.
- 27. Process by which green plants, using chlorophyll and sunlight energy, produce carbohydrates from water and carbon dioxide and release oxygen.

Down
- 1. The relative proportions of sand, silt, and clay particles in a mass of soil.
- 2. Soil or soil-like material in which plants are grown, also referred to as medium.
- 3. this nutrient helps the plant's immune system and rooting abilities
- 4. A volcanic glass having numerous concentric cracks that give rise to the perlitic structure and are used in synthetic potting media mix.
- 5. are part of the embryo and develop into the first leaves of the plant. Flowering plants are called angiosperms
- 6. This helps a plant put on lush, green growth and helps break down organic matter in compost
- 7. any material of natural or synthetic origin that is applied to soils or plant tissues to supply one or more nutrients essential to plant growth

- 22. Fibrous, partly decayed fragments of vascular plants that retain enough structure to identify the peat as originating from certain plants (e.g., sphagnum peat or sedge peat).
- 25. One cotyledon or single leaf. Parallel leaf veins and fibrous roots such as corn
