- Growth in living beings is based on the availability of oxygen, water and food. When enough food is available, the cells of living beings grow and divide. Growth can be general, to produce more of the same kind of tissue, or controlled to create new body structures and additions.

Jul 27, 2022 · Apply the principles of experimental design to your own experiments in this course and in daily life. Use biological language to describe the parts of the above-and below-ground plants parts that contribute to your diet. In Chapter 1, you’ll discover what horticulture is and how it relates to other disciplines that involve the cultivation of ...
Jul 20, 2018 · Living things can grow in two ways, based on the division and replication of living cells. To divide, cells first need to grow enough to ensure there is enough living material for two cells. Such growth takes energy, which living cells get from organic compounds such as carbohydrates.

Since they lack faces and (usually) don’t move, it’s easy to sometimes forget that plants are living things. But just like people and animals, they start out as babies, grow into adults, reproduce, grow old, and eventually die. Their requirements for staying alive are also pretty similar to ours. What do humans need to survive? Well, we need food, ...
There are three ways to acquire new plants. You can transplant established specimens, sow seeds, or propagate new plants from existing specimens. I suppose you could also buy or inherit the land that they sit in, but I’m not qualified in telling you how– I myself own no real estate. Transplanting is simply moving a grown plant from one growing site...
Acquiring a living plant is all well and good, but if you attempt to grow it in the wrong climate, then you’ll ultimately be fighting a losing battle. A plant’s hardinessrefers to its ability to survive temperature extremes. Typically, gardeners use hardiness to refer to the minimum survivable temperatures, but it can also be used to indicate the m...
Exposure is the amount of sunlight a plant receives, and getting this right is critical for optimizing photosynthesis and health. Too much light, and the leaves will “scorch,” resulting in a wilted, crispy appearance. Too little light, and the plant won’t be able to make enough food for itself, leaving its growth thin and spindly. Different exposur...
Hope you don’t mind getting your hands dirty, because soil will sully those mitts. It’s also what your plants will be growing in, so it’s worth paying attention to. Believe it or not, soil is alive. It’s a living ecosystem that contains microbes, bugs, fungi, and roots. Along with these organisms, soil is composed of mineral particles, empty pocket...
Water is essential. Plants need it for seed germination, propagation, photosynthesis, keeping cellular functions going, staying cool, and remaining upright. Without it, botanical life – and life on Earth, for that matter – wouldn’t exist. Since plants take up water through their root systems first and foremost, the roots will need access to H2O. Wh...
The glucose produced from photosynthesis provides energy to flora, but carbs alone aren’t enough. Other nutrients are also required. Don’t worry… you’ll recognize these from the periodic table. You’ve got the primary plant macronutrients of nitrogen, phosphorus, and potassium, which are needed in large amounts. Most commercial fertilizers have a th...
Many different practices fall under this umbrella, and all of them will leave your specimens better off in the long run. Pruning is one such practice, and it entails deliberately and manually removing tissues from a plant, whether by hand or via tools such as hand pruners, loppers, and saws. Pruning can be used to achieve many different gardening g...
Being a gardener isn’t all sunshine and roses, although there definitely is some of that involved (especially if you’re growing roses…). Believe it or not, gardening is a battle. A battle between you and all the pathogens, pests, and physiological conditions that could hurt, disfigure, or even kill your beloved plants. Step one in keeping your spec...
This is arguably the most important lesson of all in gardening. Flashback several years to my experience working with the aforementioned knife-throwing lady: at the time, we were both pulling weeds, a near-automatic task that allowed us to talk without doing shoddy work. On a day of nonstop wedding in the humid heat of Missouri, conversation really...
